Trials and Triumphs: All-America Selections Judging and 2024 Winners

I’ve written before about my time as a trial judge for the All-America Selections program, which I did during my seven years with Nebraska Extension. I happened upon the opportunity to be a judge by accident, but really came to relish my time and the work that the organization does.

You see, All-America Selections started in 1932 as a way to actually certify the claims that newly-introduced plants were actually better than ones already available. Previously it was sort of the wild-west of claims made by everyone who had a garden catalog or wrote a garden publication. There was no way to level the playing field and certify these claims until W. Ray Hastings, the president of the Southern Seedsman Association, established the All-America Selections trial program. As a non-profit and now part of the National Garden Bureau, the organization and its volunteer judges can serve as impartial arbiters of the superiority of newly-introduced plants.

This emblem on a seed packet or plant label indicates that the plant has gone through rigorous testing and performs well in gardens across the US (and beyond).

This is especially important in this day and age of spurious claims and piles of misinformation on the web. The organization uses a research-based approach in determining high-quality plants with replicated trials all across the country. Plants have to perform well in all regions of the country to be a winner. Sometimes if a plant does well in one area but not others, it will be considered a regional winner.

Ninety-one years later the organization still serves as the gold standard for performance in home garden plants. Judges have a track record of picking plants that are favored even decades after they are introduced. The ‘Celebrity’ tomato, winner from the class of 1984,  has probably been grown by almost everyone who grows tomatoes and can be found in almost every garden catalog or seed rack. ‘Bright Lights’ Swiss Chard, class of 1996, is also a go-to favorite for almost anyone who grows chard. And while many plant cultivars come and go with trends and company closures, there are still seven cultivars from the first class in 1933 still available for home gardeners to purchase through retailers: Tomato ‘Pritchard’, Spinach ‘Giant Nobel’, Pansy ‘ Dwarf Swiss Giants’, Nasturtium ‘Golden Gleam’, Carrot ‘Imperator’, Canterbury Tale ‘Annual Mixed’, and Cantaloupe ‘Honey Rock’. You can check out their profiles on the AAS website to see where to buy them.

2024 Winners

So far there have been 10 winners announced for the 2024 garden season. It unlikely that any more will be introduced at this point, but they often aren’t announced until they are ready to go to market so there’s always a chance. I served as a judge for the edible crops (vegetables, fruits, herbs) for both in-ground and container trials so I’ll start with the edible winners. Then I’ll also share info on the ornamental winners.  You can always find more information, including which seed and plant suppliers/retailers carry the plants, at the AAS website.

Broccoli Purple Magic F1

Broccoli Purple Magic - AAS Vegetable Winner

A striking purple broccoli with tight growth habit. Judges noted it for its great broccoli flavor that was sweeter and more tender than the green broccolis to which it was compared. It was also noted for its heat and stress tolerance.

Broccoli Skytree F1

Broccoli Skytree All-America Selections Winner

This broccoli’s long stalks set it apart. They make the compact heads easy to harvest. It is also noted that the stalks themselves are tender, sweet, and flavorful so they should be eaten as well. It is noted as being uniform and early maturing. Skytree was a regional winner in the West and Northwest. Container suitable.

Pepper Red Impact F1

All America Selections Winner Red Impact Pepper

This is a Lamuyo pepper which is a Spanish pepper noted for exceptional sweetness. It is sweeter than your standard bell pepper. The fruits are huge – nearly 8” long and double the size of standard bell peppers. We noted that they were delicious and sweet, even when green.

Celosia Burning Embers

All America Selections Winner Celoisda Burning Embers

A beautiful and long-lasting celosia in the garden. It is noted for its bronze leaves with pink veins and bright flowers. It is well-branched, heat and drought tolerant, and long-lasting in the garden. It lasted well past other types trialed. Container suitable.

Geranium Big EEZE Pink Batik

All America Selections Winner Geranium Big EZEE Pink

This geranium was noted for its long-lasting flowers and large flower heads. The prolific and large flower heads have a unique pink and white mosaic design. Judges also noted that it was very sun and heat tolerant. Container suitable.

Impatiens Interspecific Solarscape ® Pink Jewel F1

AAS Winner Impatiens-Solarscape XL Pink Jewel

Noted for the bright pink flowers with an opalescent sheen, these flowers lasted well through the season. These plants are sun tolerant and also noted as being resistant to impatient downy mildew, which has basically made it almost impossible to grow (or buy) impatiens lately. Container suitable.

Marigold Siam Gold F1

Marigold Siam Gold - National AAS Winner

This large-flowered marigold was noted for season-long performance. It was also noted that the plants didn’t need staking, even though they were tall and had large flowers making them top-heavy. Container suitable.

Petchoa Enviva™ Pink

All America Selection Winner Petchoa Enviva Pink

You might be asking yourself the same question I did – “what the hell is a petchoa?” And the answer is great – it is a hybrid cross between an Petunia and a Calibrachoa, often called Million bells. The result is a beautiful, mounding plant that is covered with large, beautiful pink iridescent flowers with yellow throats. The judges noted that plants performed well all summer, even in extreme conditions. Container suitable.

Petunia Sure Shot ™ White

The judges noted that this petunia performed like a powerhouse all season long, including extreme summer heat and weather. Most notably, the flowers kept their snow-white flowers all season, whereas many white flowers fade or get blemished quickly after blooming. Regional winner from the West, Northwest, and Great Lakes regions. Container suitable.

Verbena Sweetheart Kisses

Verbena Sweetheart Kisses

This blend of verbena has pinks, roses, reds, and whites that were super attractive to bees and other pollinators. Judges also noted the fine foliage, which isn’t like standard verbena foliage. The plants performed well all season long, even in heat and drought. Container suitable.

Petchoa – bringing together the best of the Petunia and Calibrachoa worlds

Wrapping it up

Finding that AAS seal is a great way to assure that you’re buying high performing plants for your garden. I truly did enjoy my time as a judge, even though my trials were often “if it lives through this, it definitely deserves an award” type of gardening. Now that I’ve left Extension, I’ll no longer serve as an official judge, but I still plan to volunteer to help the Extension office and serve as an “ambassador” for the AAS program. I’m glad they’ll let me stick around!

Unpacking a Peck of Purple Genetically Engineered Tomatoes

Excitement spread across social media recently with the announcement that a genetically engineered tomato, creatively named “The Purple Tomato” is now available for home gardeners. Gardeners, plant scientists, and others rejoiced at the news that a purple tomato engineered with genes from a snapdragon to boost the plant pigment anthocyanin is now available for home gardeners to purchase. But why were people so excited? And what does this mean?

The Purple Tomato: What is it and why is it exciting and important?

The Purple Tomato was developed by a company called Norfolk Healthy Produce. The company was founded by Professor Cathie Martin (and other scientists) who is a professor at the University of East Anglia and a group leader at the John Innes Centre in the UK. On February 6, 2024 they announced that seeds were available to home gardeners in the US after clearing regulatory approval hurdles by the USDA, EPA, and FDA to assure that it is safe for human consumption, for growth in US without safety containment measures, and that it does meet its claims of added nutrients. Read more about the US regulatory process here.

For all the tomato aficionados out there, The Purple Tomato is an indeterminate cherry tomato. Indeterminate means that the plant doesn’t stop growing as long as it is healthy and will produce a “vine” that needs to be staked or trellised off the ground. Production of fruits continues throughout the season starting at the bottom of the plant and going up as long as it is healthy.  Of course, it is a cherry tomato so you’ll have hundreds or thousands of tiny fruits to pick through the season. Some gardeners love growing cherry tomatoes. Others hate it for that fact. So you win some, you lose some.

Read more on indeterminate vs. determinate here.

The tomato contains two genes from snapdragon flowers that boost anthocyanin production in the tomatoes. Anthocyanins are the plant pigments responsible for blue and blue-purple colors in plants. And they are shared across all plants with these blue and blue-purple colors, so the addition of purple pigments from a flower isn’t too out of the ordinary since tomatoes already contain similar pigments. (The reddish violet/crimson color of plants in the Amaranthaceae family (beets, amaranth, chard) are from betalin pigments, not anthocyanins, FYI.) Most plant pigments actually have the added bonus of also being highly beneficial for human health as most of them are antioxidants and have other health benefits. The incorporation of anthocyanins boost the nutrient quality of tomato since anthocyanins are considered strong antioxidants. Studies also implicate anthocyanins in reducing blood pressure and heart disease, preventing neurological disease, and slowing cancer growth due to the reduction of free radicals that can damage DNA.

Now, anthocyanins in tomatoes are not new. Many hybrid and heirloom varieties of tomatoes contain anthocyanins. The tomatoes that already contain anthocyanins are the tomatoes that are often considered “purple” or “black” by seed companies and home gardeners. Like ‘Cherokee Purple’, ‘Black Beauty’, and ‘Black Krim’. However, the anthocyanins in these tomatoes are generally found in low quantities as they are only found in the skin and or the flesh just under the skin. What makes “The Purple Tomato” novel is that it is the only tomato that has the anthocyanin pigment in both the skin and throughout the tomato. Seeing pictures of the tomato, the vibrant purple color goes through the entire tomato and is striking. (It also doesn’t hurt that purple is my favorite color). Due to this purple color throughout the tomato, the fruits have a much higher concentration of anthocyanins than existing cultivars.

Another thing that excites me about The Purple Tomato is that the company claims that is an inbred/open pollinated variety. Meaning that home gardeners can save the seeds from year to year and the anthocyanin traits will continue to be present. This also signals a departure from normal genetically engineered seeds where the traits aren’t as persistent and seed saving isn’t allowed. The company does have some terms and conditions about not selling seeds (from the ones you buy or likely from any you save) and not using them to breed other varieties. But gardeners are free to save seeds and share fruits, plants, and seeds with your local community.

“GMOs” and home gardening

Despite what many people may think, until the release of this tomato there really weren’t any genetically engineered plants available to home gardeners. This marks the first time that a plant has received approval from the US government agencies that control the release of genetically engineered plant for sales directly to home gardeners. Most of the genetically engineered plants have been developed for and are available only to commodity crop (corn, soy, cotton, etc.) and select horticultural crop (papaya, some select squashes, and now Arctic apple) farmers. There’s a highly regulated process and contract procedure for farmers to obtain the seeds or plants that just isn’t practical or cost-effective for the plant developers to market to or make seeds for home gardeners.

We’ve written several times about how, until now, there really hasn’t been genetically engineered seeds available to home gardeners, despite what some seed companies would have you believe (here and here). There has unfortunately been a lot of confusion for home gardeners thanks to misguided and/or deceptive marketing practices by certain (heirloom) seed companies that labeled their “Non-GMO certified” seeds and preached about the dangers of genetic engineering to sell more of their seeds even though there have not (until now) been any “GMO” seeds available for companies to even sell to home gardeners. Unfortunately that deceptive marketing created enough fear and fervor that most seed companies had to start labeling their seeds “Non-GMO” just to preserve their sales and cut down on harassment from folks on social media trying to “call them out” for selling GMO seeds.

Not until the release of “The Purple Tomato” has there been a home garden seed that could be labeled “GMO” and warrant companies needing to label something as non-GMO. But still it is only one plant, so is it really necessary? Or is it just a marketing tactic?

Purple Tomato Reception

In cruising through the comment section on articles discussing the new tomato, I’ve been pleasantly surprised to see the positive response that it is receiving from the public. There are lots of comments excited about the prospect of a nutrient-dense genetically engineered crop, lots of excitement about buying the seed, and even excitement about the super purple color of the tomato. The few negative comments about GMOs being “bad” have gotten a lot of pushback. I don’t think this would have happened 5 or 10 years ago.

Of course, some of the pushback is a little misguided. Statements like “all plants are GMO” show a similar lack of understanding of what is actually happening, even though it is offered in good faith. Yes, humanity has guided and shaped the genetics of all of the plants we eat over the centuries and many plants have therefore been “genetically modified” by humans. But genetic engineering is a more rigorous and scientific process. This is also one of the reasons why scientists and government agencies prefer the term “genetically engineered” or “bioengineered” to GMO or genetically modified to clear up confusion.

It does seem like the tide has shifted on public acceptance of genetic engineering where until recently many people viewed the technology with skepticism and fear, thanks mainly to misunderstanding and marketing.

Much of the fear and distrust of genetically engineered plants have been around the addition of genes to make crops resistant to certain herbicides, to produce natural immunity to insects, and other traits to increase yields. Many have wrongly assumed or claimed that this has resulted in increased application of herbicides. While application of some herbicides like glyphosate has increased, it has been at the reduction of much more dangerous herbicides. These crops have often been developed and controlled by large chemical companies that, perhaps not totally incorrectly, the general public distrusts. Plus, unintended consequences like herbicide resistant weeds have caused issues.

But the new Purple Tomato goes beyond this and I think is applauded for many reasons. One – it was made solely to boost nutrition. While there have been previous (mostly unsuccessful) efforts to do this in crops (see the story of Golden Rice), this is really the first time it has been aimed at home gardeners. Two – it isn’t one of those “big scary corporations” doing it. It is a company started by academics to promote plant science and health. Three – while the plants are patented, there aren’t strict and secretive agreements against seed saving and sharing. And four – the express purpose of the plant is to increase the healthy qualities of the plant.

In conclusion

It seems like many people are excited about this new genetically engineered tomato on the market. I know that I am. It seems like the public at large is accepting and excited by this new health-boosted tomato and the technology used to make it.

I know I’ve ordered my seeds, and many others have as well. The seeds aren’t cheap, $20 for 10, but the process to make them isn’t cheap either. I’m looking forward to trying them out in my own garden.

Disclaimer: No payment or reward was received for this article promoting the Purple Tomato and I have no affiliation with the company. Norfolk Healthy Produce didn’t even know it was being written. They probably don’t even know who the Garden Professors are and they definitely don’t know who I am. That being said, if they want to reach out with some free seeds or swag, I wouldn’t be mad at them.

Po-TAY-to, po-TAH-to: Let’s call the whole yam thing off!

As most folks in the US prepare for a Thanksgiving meal, or at least eat more Thanksgiving-inspired fall meals, potatoes and sweet potatoes often play a major supporting role in these most delicious victuals.  Whether mashed, smashed, baked, candied, or turned into casseroles or pies, these starchy vegetables are stockpiled in grocery stores and markets in the fall for shoppers to turn into those tasty treats. 

But sometimes there is confusion lurking in those grocery aisles and even in the minds of unwary shoppers….enter the “yam”.  Wander down the canned vegetable aisle and you’ll see canned yams.  Are they the same thing as sweet potatoes?  And are they related to the standard potato that you usually mash, bake, or fry?  I yam going to set the set the record straight. 

First things first, sweet potatoes and yams are two totally different species so they are not the same thing.  They’re even in different plant families so they aren’t even closely related.  And neither of them are related to the regular old potato.  So those “canned yams” at the grocery store are mis-named.  They are sweet potatoes.  Yams are rarely consumed or sold in the US, except usually though markets that sell specifically African/Caribbean foods. 

A sweet potato in bloom….look familiar?

Sweet potatoes are soft when cooked, thin/soft skinned, usually pretty sweet, and usually orange.  Though there are some white-fleshed, less sweet varieties available.  Native to tropical regions of the Americas sweet potatoes, or Ipomoea batatas, are members of the Convolvulaceae, or bindweed, family and are closely related to morning glories many of which are in the same genus Ipomoea.  These sweet veggies are part of the root structure, so they are modified storage roots that store starches and sugars produced by the plant. 

Yams, on the other hand, are white with a hard skin like tree bark, and are usually pretty dry when cooked.  There are three main species of yams in the Dioscorea genus, which has its own family Discoreacea.  Also tropical in nature, three different species were domesticated independently in Africa (D. rotundata), Asia (D. alata), and the Americas (D. trifida).   Yams are monocots, meaning they are more closely related to lilies and onions than they are to sweet potatoes.  Also, unlike sweet potatoes, the edible portion of a yam is a tuber, which is structure arising from modified stem tissue. 

Piles of yams…that look nothing like sweet potatoes

And just to round out the tater trifecta – the humble potato.  Sometimes called a white potato or an Irish potato (which are both bad descriptors for them because they come in many different colors, and while they are a staple in Ireland they originate from the Americas), these versatile spuds, Solaunum tuberosum, are members of the Solanaceae family and are closely related to tomatoes, Solanum lycopersicum.  Their morphology has similarities to those of the yam, though, as they are tubers arising from the stem vs being a root like sweet potatoes. 

So where does all the confusion come from? 

There are various theories on how yams and sweet potatoes got caught up in this mash-up, and I don’t pretend to be an expert here.  But the most common theory that I’ve seen is that enslaved African people held in the US south called the local sweet potatoes by the names they used for yams, as the sweet potatoes reminded them of the yam that was part of the staple diet in many African countries.  The word yam is derived from nyam, nyami, or nyambi, meaning “to taste” or “to eat” in certain African language dialects.  Adding to the story, apparently Louisiana sweet potato growers in the 1930s used “yams” as a marketing name for a new orange-fleshed sweet potato cultivar and the name stuck. 

One thing I find interesting is that yam was used to describe orange sweet potatoes when the white fleshed ones (which are less common now) would probably more resemble an actual yam, both in appearance and flavor.  In fact, in my travels in Rwanda I ate many white fleshed sweet potatoes, as they are now a major staple crop in many African countries.  It is also interesting to note that the refugee farmers in our urban farm programs prefer to grow the starchier, less sweet varieties of sweet potatoes, which often complicates things as they can be hard (and expensive) to find. 

Whether you cook sweet potatoes or “white” potatoes for your Thanksgiving feast, now you’ll know a little bit about how each of those crops are different…and you’ll at least know that sweet potatoes aren’t yams. 

Poinsettias: from ditch weed to holiday super star (history, lore, and how to get those d@!% things to rebloom next year)

The holiday season creeps earlier and earlier each year, at least here in the US. Decorations, trinkets, and more start filling store shelves before summer is even over. But some holiday traditions can’t be rushed, like live holiday plants. Many of these picky plants have to be bought and cared for closer to the holidays, else they likely won’t look so festive once the holiday finally arrives. Since the origins of many of the holiday traditions are pagan and druid in nature, it stands to reason that plants are a major theme for the holidays. I’ve written before about the origins of using the plant parasite mistletoe as a holiday decoration and invitation for lip locking. And also about how what most people call a Christmas cactus is actually a Thanksgiving cactus and they are actually two different things (and there’s also a Spring/Easter cactus as well. We have amaryllis, paperwhites, cyclamen, Norfolk Island pines, pine-shaped rosemary plants, and more that make up our usual holiday decor. But none are so vibrant and indicative of the holiday as the poinsettia. So let’s talk a little about the history and lore of this plant and also about how day length affects its colorful holiday display. Just in case you want to try saving one from year to year.

Poinsettias take center stage as a 25 ft tall tree at Lauritzen Gardens in Omaha, NE each holiday season.

What is a poinsettia, anyway? It doesn’t really look like other plants.

This plant is a standout in the mostly weed-filled and much-maligned spurge family Euphorbiaceae. This family includes lots of different plants that take on a variety of forms. It does include many weeds, but also many houseplants that have much more of a cactus form than poinsettia.  Relatives you might find as houseplants include a cactus-like plant with leaves on its margins (mainly just called Euphorbia), a plant called crown of thorns and a sticklike plant called pencil cactus. It is a weird family. Most of them do have a sap that can cause dermatitis in the skin or a stomach ache if ingested. But poinsettia has earned an incorrect reputation as being poisonous and a plant to steer clear of if you have kids or pets. Sure, ingestion might cause a tummy ache and associated symptoms, but the amount of poinsettia one would have to eat to actually have life-threatening symptoms is astronomical.

These ugly bits in the center are the actual flowers of the poinsettia.

While we enjoy poinsettias for their bright colors, it would be incorrect to say that poinsettias have large, colorful blooms. The colors that we see are called bracts — brightly colored leaves.  These bracts change color much the same way leaves change color in the fall: They lose their green chlorophyll to expose the color beneath. This happens when the flowers, those ugly little yellowish lumps in the middle of the bract, mature.  

While the classic red poinsettia (pronounced poin-SEH-tee-uh, not poin-SEH-tuh, by the way) lends itself to the classic colors of Christmas, it might be hard to figure out how this weed from Mexico found its way to the top of the list of traditional holiday plants. After all, it is a much more recent addition to the holiday decoration arsenal than the evergreens borrowed from ancient pagan rituals. And while we most often think of red poinsettias, there are hundreds and thousands of different cultivars and colors – and we’ve even taken to spraying them with dye and glitter (shudder).

Poinsettias these days come in all shapes and sizes and colors.

Poinsettias are famous for having a difficult blooming process. The plants are considered short day plants, thought the more accurate description would be a long night plant. This means that in order to set blooms, the plant needs a few weeks where it receives at least 12, and preferably 16, hours of uninterrupted darkness each night. This creates physiological and chemical cues that allow for development of floral structures, which in turn result in development of the colorful bracts. Even a few seconds of light in the middle of the night can stop, interrupt, or delay the process. This often makes saving poinsettias from year to year difficult, and can even make it difficult for commercial growers to provide darkness in our ever (artificially) brighter night sky.

How did a weed get associated with Christmas?

The poinsettia (Euphorbia pulcherrima) is a native plant (and can grow as a fairly large shrub or tree) in Mexico. The original name used for the plant, prior to Americanization, was cuetlaxochitl.  I’ve seen them in several places around the world, including one as big as a tree in Kigali, Rwanda (other Euphorbia, like the pencil cactus also grow there). A local Mexican legend from the 14th century explains that a young girl on her way to Christmas Eve mass was upset that she had no gift for the baby Jesus and picked a handful of weeds on her way to church.  As she placed the humble bundle of weeds on the altar, they erupted into brilliant red, and all those around exclaimed that it was a Christmas miracle.

Aside from the miracle legend associated with the flower, there are other connections between the plant and the holidays. The traditional red of the poinsettia is cited by many as a representation of a blood sacrifice and the shape of the flower as the Star of Bethlehem.  Before poinsettias became a worldwide symbol of the holidays, Franciscan friars included the vivid plants in Christmas celebrations in the 17th century.  In Mexico, the plant is also known as Flor de Nochebuena, or Holy Night (Christmas Eve) Flower.

From ditchweed to international holiday superstar

The poinsettia really didn’t come into its current fame until it was introduced to the United States in 1825, at the hands of a politician.  It just so happened that the first U.S. minister to Mexico (this was before we had ambassadors) was an amateur botanist. He brought the plant back to his private hothouses in South Carolina, and then shared it with friends (including renowned botanist John Bartram) who introduced the plant to the nursery trade.  It filled an empty spot in the nursery calendar, so nurseries were quick to embrace the plant.

This is the guy who brought you the poinsettia, and so much more.

The plant quickly was renamed Poinsettia (it was originally sold under its botanical name) in honor of the man who brought it to the country — Joel Roberts Poinsett.  His contribution to the plant’s history and the nursery business in the U.S. was honored by Congress, which has declared Dec. 12 National Poinsettia Day. A date which, oddly, commemorates the date of Minister Poinsett’s death.

Aside from his botanical triumph and service as minister to Mexico, Poinsett was also an “agent” to Chile and Argentina, a state representative, a member of the U.S. House of Representatives and secretary of war.  Most people would be surprised to learn that the man who brought you the poinsettia also oversaw the removal of Cherokees from North Carolina to Indian Territory in 1838 and the military during the second Seminole War. But he was also involved in the Columbian Institute for the Promotion of Arts and Sciences and a co-founder of the National Institute for the Promotion of the Sciences and Useful Arts.

This national institute, composed of politicians, promoted the use of the Smithson bequest to form a national museum. While they were defeated in their efforts, the institute went on to become part of the result of the Smithson bequest — the Smithsonian Institution.

The poinsettia didn’t become common holiday fair for the general masses until Paul Ecke Sr., a German immigrant living in California started growing them on a large scale. Ecke and family were also responsible for breeding poinsettias, turning them in to a weedy plant in to the more robust, bushy form we see today. While the Ecke family has moved a lot of production overseas, they are still responsible for 70% of the poinsettias sold in the US and nearly half of all poinsettias sold worldwide.

So, how can I save my poinsettia and get it to rebloom next year?

In theory, this is pretty simple, but as GP alum Holly Scoggins points out it can be difficult to keep these plants happy and healthy, let alone get them to rebloom so that the bracts will color up.

But if you do want to save your poinsettia from year to year, here’s how to do it:

  1. Keep your poinsettia in a bright but cool spot to keep it colorful longer. When the leaves start to yellow, or you are done with it for the season, slowly reduce watering until it loses all leaves (and colorful bracts, which will be last to go) and goes dormant.
  2. Store the plant in a cool (50-60 F), dry, and dark area. Keep the soil on the dry side, but water just enough to keep the stems from drying out.
  3. After the danger of frost has passed, or in April or May (if you don’t have frost), remove the plant from storage and repot. Use a good quality and light soil mix – poinsettias do not do well with heavy soils. And it turns out that since poinsettias are typically sold as disposable plants, the soil they come in is crap (even high end houseplants these days come in cheap, crappy soil). Practice root washing to remove all the old soil and pot up to a larger size if the plant seems root bound.
  4. Place the plant outside if possible after the danger of frost has passed, or grow in a bright, sunny window. Keep humid, well watered, and fertilized throughout the growing season.
  5. As the danger of frost approaches, move the plant indoors in a bright, sunny window (if it isn’t kept indoors). Ideal temperatures are 75F during the day and 60-65F during the night.
  6. In late September or early October, move the plant to an area that receives no light at night, even from outdoor street lights. The easiest way to provide exact light and dark needs would be in a dark room with lights on a timer. Provide no fewer than 12, and preferably 14-16 hours of uninterrupted darkness and 8-12 hours of light per day. Alternately, you can move the plant to a dark room or closet for its dark period.
  7. After flowers begin to form and bracts start to change color, move to a preferred place in the home for the holidays. Continue to keep the plant well watered, and regularly fertilized through the holiday season.
  8. Rinse and repeat, if desired.

Houseplant Hubub: The rage about variegation

It is no secret that houseplants are hot right now.  Interest was growing before the pandemic, especially with millennials and younger folks.  Then the pandemic hit.  Houseplant interest skyrocketed since people were stuck at home and wanted to bring a little bit of nature indoors to make their spaces a little more cozy for 24/7 habitation. 

This has caused the demand, and price, of many houseplants to increase, especially if they are on the rarer side.  One thing that increases the price of many plants is when a variegated version of a standard plant has been developed. 

My reading nook/houseplant oasis

Just as an example, after posting a photo of my “reading nook/houseplant oasis” in my home office I was informed that variegated form of a Monstera deliciosa vine that I had was the highly sought M. deliciosa “Albo-Variegata” cultivar, usually referred to as a Monstera albo, or just Albo.  Folks were reaching out to buy cuttings right and left.  I ended up selling 5 single leaf/node cuttings over one weekend and made $675 in the process.  That’s right, $675!  The most variegated of the leaves sold for $200, and that was actually a bargain price.  The garden writer for the local paper, the Omaha World Herald, even picked up the story and shared it as a focus on the four new houseplant shops that have popped up in the city over the last few months.

Had my plant not had the variegation that made it an albo, each of those cutting would have been worth a few dollars apiece.  So what makes some plants variegated and others not?  Sometimes the variegation is the standard form found “in nature” and sometimes it is a cultivar or variety that has been bred or discovered by chance.  Let’s take a look at all the ways that a plant can get that variegation, whether it is standard or rare. 

Chimeric variegation

My Monstera albo that caused the hubub

This is a common form of variegation and the one responsible for the variegation of my Monstera.  In this form, a genetic mutation in some cells changes that cell’s ability to produce chlorophyll.  It may reduce chlorophyll production, resulting in yellowish or silver coloration, or eliminate chlorophyll altogether, resulting in white coloration. 

The name chimeric or chimeral is based on the fact that the plant displays two (or more) chromosomal patterns on one plant.  In Greek mythology, a Chimera is a frightening fire-breathing female monster with the head of a lion, body of a goat, and the tail of a serpent. 

Image result for chimera

This variegation can be stable, where the pattern persists throughout the plant.  Or it may be unstable, where it is random on certain leaves and parts of the plant can revert back to the standard green form.  These plants can also produce leaves that are almost totally white, which usually results in a leaf that will die since it can’t photosynthesize. 

This type of variegation also means that cutting or propagations may or may not be “true” to the pattern.  It can be random.  For my Monstera, the presence of white striping in or around the node that will become the new plant is the important marker for whether the new plant will be variegated or not. 

One common chimeric houseplant is the plant formerly known as Sanseveria, now a Dracena (Snake plant or mother-in-law’s tongue). Many of the different color patterns on some of the cultivars are due to cuttings taken from different parts of the “original” natural type that display different colors on them.

Viral variegation that was all the rage in Tulip Mania

While beautiful, this variegation will often reduce the productivity of plants if not kill them outright.  There aren’t a lot of houseplants that have this variegation, but some Hosta cultivars do.  Probably the most famous case of viral variegation is the Tulip Mania during the Dutch Golden Age (in the 1600s).  Prices of tulips skyrocketed and people were buying them as investments (maybe like the current houseplant craze, or GameStop stocks, or bitcoins).  Unfortunately, as the virus reproduced plants kept getting weaker and weaker.  Eventually the tulip market collapsed and lots of people went broke.  Let’s hope that doesn’t happen with the houseplant market….at least with my fancy Monstera. 

Natural Variegation

Natural variegation on Tradescantia

This type of variation occurs when the patterns or colors of the variegation are written into the DNA of the whole plant.  It will occur regularly throughout the entire plant, not randomly on some parts as in chimeric or viral variegation.  This variegation is passed through cuttings and usually through sexual reproduction from seeds as well, though different variations may pop up that cause a more desirable or rare cultivar. 

Common houseplants such as Tradescantia, Maranta (prayer plant), and many more common plants have this type of variegation. 

Blister, bubble, or Reflective Variegation

Reflective variegation on Phildodendron ‘Birkin’ following veins in the leaf

This type of variegation occurs when there is an air pocket or bubble between the lower layer of tissue and epidermis, or skin, of the leaf.  The lower level typically has green pigmentation from chlorophyll and the epidermis does not, resulting in a pattern that is usually white, silver, or yellowish though other colors could appear.  This pattern can be blotchy or splotchy like in some types of Pothos and Pepperomia.  It can also occur along the veins of some plants, resulting in white or silver veins on green leaves, as in some Alocacia, Anthurium, and Philodendron varieties. 

In conclusion…..

Even if you don’t have an expensive plant hiding in the corner, houseplants can add lots of fun and color to your living spaces.  And sometimes, your houseplant obsession can even pay for itself.  Online swap and sale groups have houseplant afficionados swapping and selling cuttings and plants all over the place.  So enjoy your plants….and maybe you’ll find a cash cow hiding in the corner.  Don’t mind me….I’m just over here propagating more Albos to fill up my “mad money” jar.

Testing, testing, 1-2-3: Trialing new plants for the home garden

How do you know that plants will do well in your garden?  Do you research the types of plants for your region, study different cultivars, and select only things that have been proven to do well for your conditions?  Or do you buy what catches your eye at the garden center, plant it, and then see what happens?  I used to joke that my home garden was a horticulture experiment station, since I’d try all kinds of random plants or techniques and see what works for me.  Now, I get to do that as a fun part of my job through the All-America Selections (AAS) program. You’ve likely seen the AAS symbol on plants or seed packets at the garden center or in catalogs.  Heck, you may even have them in your garden (and not know it).  I compare it to the “Good Housekeeping Seal of Approval” that you used to see on appliances, cleaners, etc. The AAS program is a non-profit started in the 1930’s with the goal of evaluating new plants so that home gardeners can purchase high quality seeds and plants and to assist the horticulture industry in marketing innovations from their breeding programs.  You can read more about AAS and its history here.

A few weeks ago I traveled to Chicago for the All-America Selections (AAS) Annual Summit to receive their Judge Ambassador Award.  I had signed up a few years ago to be a trial site for edible crops for AAS.  The following year I talked my colleague Scott into signing up as a judge for their ornamental trials.  The fun thing about the program is that we get to grow all kinds of vegetables, fruits, and flowers that aren’t even on the market yet.  We get to see how well they grow compared to similar plants and rate them on a number of factors including growth habit, disease resistance, and performance plus flavor (for edible crops) or flower color/form (for ornamentals).  It can be hard work, but it is rewarding to help identify true plant innovations and to see your favorites be announced as winners.

How the testing works
While the AAS Trials may not have the rigor of academic crop research, I do appreciate the procedures in place that provide objective and high standard results.

Breeders, developers, and horticultural companies submit their new plants that are planned for future introduction to the board of AAS for consideration in the trialing program.  During the application process, novel traits of the plants are identified to ensure that the plant offers something new and exciting – these are the traits that judges will observe and score.  The board reviews the application to determine if it fits within the program rules.

Planting the vegetable/fruit trials.

One great thing about the program is that trial judges are professional horticulturalists from universities, seed companies, botanical gardens, etc. – they’re people who know how to grow things and know what quality plants look and act like.  There are trial sites all around the country, providing for replication and generalizeable results for most regions of the country. The conditions plants are grown in also vary by location.  My trial is at a farm where management is minimal.  When we were at the summit we visited the trial gardens at Ball Horticulture which looked much more maintained and pampered compared to mine.  This gives data on a variety of maintenance levels as you’ll find in home gardens – some gardeners are very conscientious about maintaining their plants and others have a more laissez faire approach.  In order to win as a full national AAS winner, the plants have to perform well across the country in all these different situations.  Sometimes those that perform well in a few regions but not the others will be designated as regional winners.

Second, the tests are blind.  This means that we do not know what the exact plant is, who the breeder or seed company is, or any other info other than what type of plant it is.  To the judge, each entry is just a number.  It could be from a seed company you love (or hate), your best friend, the breeder who was your advisor from grad school, etc.  This makes the results fair and reduces the chance for bias toward or against a plant based on its origins.  The ratings are just based on the plant.

Another part of the trial is comparison.  It is one thing to grow a tomato plant and say “yep, that’s a good tomato.”  Its another to grow a tomato and compare it to similar cultivars to say “yep, that’s a good tomato….but it is better than what’s already available on the market.”  The goal of the program is to show how new plants have merit over older plants.  We only need so many new tomatoes (and let’s face it, there are lots of new tomatoes – we test WAY too many in the AAS process for my liking).  The board of AAS judges reads the entry info from the new cultivar being tested and selects plants (usually two) to compare it against.  If the trial is a yellow cherry tomato, it will be grown and tested alongside other yellow cherry tomatoes.  The scoring is based on whether its performance or taste is as good as or better than the comparisons.  If most judges don’t rank it as “better” then it has no chance of winning.

Confidentiality and Proprietary Plants

The fact that the testing is blind, paired with the fact that results of “failed” tests are not released, lends itself to confidentiality.  Another important factor about the testing is the proprietary nature of the tests and test sites.  These are new plants that haven’t been introduced to the market (except for the case of perennial trials) and are usually for proprietary or patented plants.  Test sites should have some sort of control over who enters them and signs prohibiting the collection of seeds, pollen, or cuttings are placed at the site.  Believe it or not, the world of plant introductions can be dog-eat-dog and cutthroat.

So what if it doesn’t win?

One of the cool things about the test is seeing the announcements of the winners early the following year.  You see the list of plants and think back to what you grew the previous season.  If often find myself thinking “oh yeah, I remember that plant, it did really well” and sometimes even “how did that win, it did horrible for me.”  This is a good reminder that we can’t base generalized garden recommendations on anecdotal evidence.  What did well for me may not work for someone else and vice versa.  All the results from the test sites go together to provide a general view of the plant performance.  It will do well for some and not others.

So if most of the judges rank the crop as not performing, looking, or tasting as good as the comparisons the plant doesn’t win.  And that’s it.  Due to the confidential nature of the testing you won’t know that it failed the test.  Even I won’t know that it failed the test. It will likely go on to market without the AAS seal where it will face an even tougher test – the test of consumer demand.  Of course, many people may grow it and be successful, and some may grow it without success.

What are the AAS Winners and how do I find them?

There’s a list of plants announced each year through the AAS website and social media channels.  You can find a list, in reverse order of winning (meaning most recent first) on the AAS Website.  The site also has a searchable database if you’re looking for a specific plant.  Since these plants are owned by lots of different seed companies and breeders, there’s also a retailer listing on the site.  The AAS program also supports a number of Display Gardens across the country, including botanical gardens, university gardens, and others where the public can see the most recent winners growing.  Here in Omaha we maintain a display garden for the ornamental plants at our county fairgrounds.  We also have our on-campus garden which is used for our TV show Backyard Farmer (the longest running educational TV program in the country, BTW) which serves as a display garden for both ornamental and edible crops.

I recently shared the AAS Testing Program with the local news here in Omaha. Check it out:

The Myth, the Legend, the Parasite: Romance, Lore, and Science beneath the Mistletoe

As we hurdle ever closer to the holidays and the end of the year, there’s lots of plants we could talk about – amaryllis, poinsettias (and the abuse thereof with glitter and paint), whether or not your cactus celebrates Thanksgiving, Christmas, Easter or is agnostic, and on and on.  Each of these plants have an interesting history and connection to the holidays, but today we’re going to be a little more naughty…but nice.  We’re going to talk about mistletoe.

Now, mistletoe is one of those holiday plants that you don’t really want growing in your own garden. That’s because, even though it is a symbol of love and even peace, it truly is a parasite … and poisonous. It has been celebrated and even worshipped for centuries, and still has a “naughty but nice” place in holiday celebrations.

Burl Ives, as the loveable, banjo-playing, umbrella-toting and story-narrating snowman in the classic “Rudolph the Red-Nosed Reindeer” claymation cartoon tells us that one of the secrets to a “Holly Jolly Christmas” is the “mistletoe hung where you can see.” But where does this tradition of giving someone an innocent (or not-so-innocent) peck on the cheek whenever you find yourselves beneath the mistletoe come from? And just what is mistletoe anyway?

While mistletoe specialists need mistletoe, the reverse does not hold—mistletoe in many regions is dispersed solely by dietary generalists.

There are around 1500 species of mistletoe around the world, mainly in tropical and warmer climates, distributed on every continent except Antarctica.  In North America, the majority of mistletoe grows in the warmer southern states and Mexico, but some species can be found in the northern US and Canada.  A wide variety of birds feed on the berries of mistletoe and thus disperse seeds.  These birds include generalists who opportunistically feed on mistletoe, and specialists who rely on the berries as a major food source.

First, we’ll cover the not-so-romantic bits of this little plant.  Mistletoe is a parasitic plant that grows in a variety of tree species by sinking root-like structures called haustoria into the branches of its host trees to obtain nutrients and nourishment. It provides nothing in return to the tree, which is why it is considered a parasite.

Mistletoe grows and spreads relatively slowly, so it typically does not pose an immediate risk to most trees.  While a few small colonies of mistletoe may not cause problems, trees with heavy infestations of mistletoe could have reduced vigor, stunting, or susceptibility to other issues like disease, drought, and heat. So be on the lookout for mistletoe in your trees and monitor it’s progression.

This little plant does have a long and storied history — from Norse mythology, to the Druids, and then finally European Christmas celebrations. Perhaps one of the most interesting things about the plant is the name. While there are varying sources for the name, the most generally accepted (and funniest) origin is German “mist” (dung) and “tang” (branch). A rough translation, then, would be “poop on a stick,” which comes from the fact that the plants are spread from tree to tree through seeds in bird droppings.

“Baldur’s Death” by Christoffer Wilhelm Eckersberg (1817)

In Norse mythology, the goddess Frigga (or Fricka for fans of Wagner’s operas) was an overprotective mother who made every object on Earth promise not to hurt her son, Baldr. She, of course, overlooked mistletoe because it was too small and young to do any harm. Finding this out, the trickster god Loki made a spear from mistletoe and gave it to Baldr’s blind brother Hod and tricked him into throwing it at Baldr (it was apparently a pastime to bounce objects off of Baldr, since he couldn’t be hurt).

Baldr, of course, died and Frigga was devastated. The white berries of the mistletoe are said to represent her tears, and as a memorial to her son she declared that the plant should represent love and that no harm should befall anyone standing beneath its branches.

The ancient Druids also held mistletoe in high esteem, so high that it could almost be called worship. During winter solstice celebrations, the Druids would harvest mistletoe from oak trees (which is rare — oak is not a common tree to see mistletoe in) using a golden sickle. The sprigs of mistletoe, which were not allowed to touch the ground, would then be distributed for people to hang above their doorways to ward off evil spirits.

While the collecting and displaying of mistletoe was likely incorporated into celebrations when Christmas became widespread in Europe in the third century, we don’t really see mention of it used specifically as a Christmas decoration until the 17th century. Custom dictates that mistletoe be hung in the home on Christmas Eve to protect the home, where it can stay until the next Christmas Eve or be removed on Candlemas (which is Feb. 2). The custom of kissing beneath the parasitic plant isn’t seen as part of the celebration until a century later.

Washington Irving, who more or less reinvigorated the celebration of Christmas in the United States in his day and whose writings still define the idyllic American Christmas celebration, reminisced quite humorously about mistletoe and Christmas from his travels to England. He wrote:

“Here were kept up the old games … [and] the Yule log and Christmas candle were regularly burnt, and the mistletoe with its white berries hung up, to the imminent peril of all the pretty housemaids.”

Whether or not your housemaids will be in peril, the hanging of the mistletoe can be a fun Christmas tradition. Look for it at garden centers and Christmas tree lots this season.  Or maybe you can find some growing wild and harvest it for your own decor. However, I would recommend not getting it out of the trees the “old Southern way” — shooting it out with a shotgun.

My cucurbits won’t stop having sex.

Not really a botanically-correct statement, but you know what I mean. John Porter’s previous blog post did a great job of explaining cucurbit reproduction (loved the Pucchini). Though I was surprised to learn “not getting any fruit” is actually a problem. Can’t say I’ve had an issue with that, ever. We have a really vibrant bee population and they’ve been super busy.

I love growing squash of all sorts, despite not being a terribly gifted vegetable garder. Past Garden Professors posts have addressed this issue. One might ask, why on earth would a two-person household need a 60-foot-long row of zucchini? Because we can!  Though if I recall, I intended to go back and thin the row. Whoops.

The zucchini hedge. And those aren’t weeds, they’re *biodiversity*.

By late summer, we usually end up with gummy stem blight, powder mildew or squash stem borer  No sign yet, though any of these goodies could show up next week. The plants are all healthy and ridiculously enormous. It’s been very warm and dry, but we have a nice drip irrigation system in place.

So guess what happened when we got too busy to check on them for three days?   Many more were still on the plants when I snapped this pic. I’ve worked zucchini in some form into every meal except breakfast. Joel’s still being a good sport. Next step is anonymous *gift* bags to folks at the office. Though I think I’m getting a reputation.

Normal-sized zucchini at top of photo for reference.  Aargh.

Not all zucchini taste alike, as true fans know. The pale hybrid Bossa Nova, right, has very creamy and tender flesh with seeds that are really only noticeable when it gets, er, hefty. Bossa Nova is a recent All-America Selection and perfect for use with those spiralizer thingies.  The ribbed/striped variety is Costata Romensco – an heirloom variety with really wonderful flavor. Humongous plants though, probably not the best choice for square foot gardening fans. Tigress is the white-flecked green selection, allegedly more disease resistant than most. Bright and sunny Gold Rush, an old-school AAS selection, adds some color and is a bit sturdier/keeps longer than yellow summer squash.

I won’t be trying to save seeds – as John noted, can be very tricky/futile when there are other cucurbits about. Plus it’s too much fun to pick out next year’s selections from the winter seed catalogs, when the prospect of bountiful zucchini stacked like firewood actually sounds appealing.

 

 

 

 

Notes from the botanical etymology division, toxicology subcommittee

By Charlie Rohwer (Visiting Professor)

The recent assassination attempt England, interesting and significant geopolitically, has reminded me about one of my favorite Latin plant names. A report on the radio stated that atropine therapy is used to treat the specific poison involved in the attempt. To paraphrase Dr. Randy Pausch, “I’m a doctor, but not the kind who helps people.” Therefore, I have no authority on the medical uses of atropine. The world Health Organization lists it as a preoperative anesthetic on its list of essential medicines, so it must be pretty important.

Atropa belladonna, Leipzig botanical garden

But I do like horticulture and I like words. That’s where my interests lie in relation to this story. Many medicines are or have been plant-based. Atropine itself comes from certain plants in the nightshade family. Like any chemical people use, dosage of atropine determines its effects; atropine can be medically useful, or it can be deadly. The drug is named after a specific plant from which atropine can be obtained, Atropa belladonna. The omnibotanist Linnaeus named it in 1753 (can someone come up with a better word for him than ‘omnibotanist?’).

‘Belladonna,’ as it’s commonly called, is a small shrub native to Europe and Asia. ‘Belladonna’ comes from the Italian words ‘bella’ and ‘donna,’ meaning ‘beautiful woman.’ An extract from the plant was applied topically to eyes during the Renaissance to dilate pupils. One sign of sexual arousal is dilated pupils, so the extract would cause a response that looked like sexual arousal. If you were a lady going to a fancy party during the Renaissance and you wanted to look beautiful, belladonna may have helped (according to beauty standards of the time). My optometrist told me atropine isn’t used for retinal exams today because its effects last too long.

Dilated pupil

The other common name for Atropa belladonna is ‘deadly nightshade.’ The drug, atropine, is made of two isomers of hyoscyamine, made by the plant (and some other related plants). At some doses, hyoscyamine causes muscles to relax (like the iris, for example) due to its effects on nerves that control muscles. At larger doses, it can kill because you need muscles to breathe and to pump blood at a reasonable rate. Dosage and route of entry are important!

The author with one of his favorite books.

So Atropa belladonna was used to make ladies beautiful, hence the epithet ‘belladonna.’ But what about ‘Atropa?’ What’s that mean? Where does the drug atropine ultimately get its name? My favorite book as a kid was “D’Aulaires’ Book of Greek Myths.” Linneaus borrowed from the Greek myth of the three Fates in order to name deadly nightshade. According to D’Aulaires, these goddesses of destiny “…knew the past and the future, and even Zeus had no power to sway their decisions.” Nobody can escape fate. The three fates were named Clotho, Lachesis, and Atropos. The fates are responsible for the thread of everybody’s life. Clotho spins the thread at birth, Lachesis measures it out and determines destiny (what’s on the thread and how long it is), and Atropos (‘inflexible’ or ‘unturnable’) cuts the thread after Lachesis has apportioned it. Atropos is the goddess directly responsible for the end of everyone’s thread of life, and her action is final.

The Three Fates

Atropa belladonna simultaneously means something like ‘inevitable, inflexible death’ AND ‘beautiful lady.’ Indeed, the dose makes the poison.

 

Howdy and Previous Post Revisited 1.0

Greetings all, and good to be back in the saddle for the Garden Professors.  It’s been a while since I’ve filled you in on my own personal gardening struggles (lots) and triumphs (few) as well as topics I think you’d be interested in.  I’ve always appreciated the kind comments and good questions our readers pose, in response to my off-kilter posts and horrific punctuation.

I’m sure there is one BURNING question that long-time readers have:

“So how’s your Puya doing?”

“Fine, thank you!”

Well, mostly.

Long story short, I bought/committed to a Puya berteroniana in 2012.  If you have no idea what I’m talking about: http://gardenprofessors.com/puya-report/

I’m sure many readers have been at the receiving end of a cactus spine or Agave poke; the genus Puya makes Agaves look like stuffed animals.  Fish hooks line the margins of each leaf, and cascade over the side of the pot. Therein lies the problem…

Still alive, and doing pretty well, but Pootie the Puya really needs re-potting to realize her full potential (the blooms are outrageous, and the point of all this, as I mention here: http://gardenprofessors.com/the-eternal-gardening-optimist/)

I’ve attempted to “go in” a couple of times, but even leather grilling gloves get snagged. Need really strong tongs (two sets?).  I’m probably going to have to just bust the pot.  She didn’t make it out to the deck this summer due to the awkward pot situation. Suggestions welcome, especially from anyone who has wrestled with one of these (and lived)!
