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!

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:
