Corny Ancestry

I love growing weird plants, and I’m endlessly fascinated by plant breeding and the extreme transformations humans have made in our crop plants over the history of agriculture.

Which is why growing teosinte, the wild ancestor of corn, was a no brainer. Even before I planted it, comparing the seeds is fascinating. teocornseed

Once growing you can see the similarity. Teosinte is on the left in the picture below, corn on the right.

teocorn

The most dramatic difference between the two, I think, is the “ear” of teosinte, which is nothing more than a thin sprig of half-a-dozen seeds.… Continue reading this article “Corny Ancestry”

Perennial Funday: Rudbeckia grandiflora ‘Sundance’

Just back from the always-inspirational Perennial Plant Association Symposium, this year held in Baltimore.   The theme celebrated the massive influence of German plantsmen and designers on both the mid-Atlantic and the perennial business as a whole. Whether a grower, garden center owner, or landscape designer, the names historically associated with Mid-Atlantic horticulture – Kurt Bluemel, Oehme, van Sweden & Associates, etc. – resonated with all attendees.

The history of the “perennials movement” was recounted – where the Germans (and more than a few Dutch) admired, utilized, and selected cultivars of our fabulous summer and fall-blooming native perennials – long before we North Americans ceased relegating them to ditch weeds.  … Continue reading this article “Perennial Funday: Rudbeckia grandiflora ‘Sundance’”

Hey, Consumer Reports Wrote Back! And Yes, They Are Comfortable Recommending Useless Chemicals That Might Cause Cancer!

Two weeks ago I wrote an open letter to Consumer Reports voicing my concerns about some recent articles they had published regarding lawn and garden care, as well as reiterating some issues that Linda Chalker-Scott Ph.D. had with one of their stories. You can read the article for yourself, but the long and short of it is that they made some weed control recommendations that don’t work and recommended a chemical which might cause cancer.… Continue reading this article “Hey, Consumer Reports Wrote Back!

Out of the bottle and into the bag

Last week I was having lunch with my mom at our favorite nearby nursery/café. After failing to resist the grilled cheese sandwich (3 cheeses! And buttery panini bread!), we walked off lunch in the garden supply part of the nursery. Normally I’m on my best behavior when I’m shopping with my mom (i.e. I don’t take photos of things I’m going to take to task on the blog). But like the 3-cheese grilled sandwich I was unable to resist the bags of biodynamic compost.… Continue reading this article “Out of the bottle and into the bag”

James Kennedy on Chemistry

 

 

Sometime in the last twenty years or so, the word “chemical” has become a dirty word.  Hard to pronounce words. Unnatural synthesized substances. Mad scientist concoctions brewed in a laboratory.

I used to try to introduce some perspective when I facilitated pesticide workshops for the general public by teaching how scientists and regulators determined toxicity, so comparisons between familiar substances, like caffeine, aspirin, or detergents could be made, to varying degrees of success.

It was the “unnatural synthesized substances” part that I had the most difficulty overcoming.… Continue reading this article “James Kennedy on Chemistry”

Show me the data!

One of my favorite bumper stickers from days gone by said simply “Stop Continental Drift”. Good luck with that.

stop_continental_drift_530

Today’s topic deals with another type of drift – a phenomenon one of my professors referred at ‘Bibliographic drift’.   This type of drift occurs when authors cite a paper without bothering to look up the original source.  Then a second author cites original source based on the first author’s paper; then a third author cites it based on the second paper and so on and so forth. … Continue reading this article “Show me the data!”

Why doesn’t my plant flower? Part 1

I often get horticulture questions from county extension agents, Green Industry professional, gardeners and my next door neighbors. One of the most common questions I get is why their plant did not flower that year. There are many reasons why a plant, either woody or herbaceous perennial, will not flower and both new and established plants can be affected. Some of the below reasons are obvious, some not so obvious.

There may be several reasons why a landscape plant does not flower (more to come next week):

1) Plants requiring full sun are not receiving enough sunlight.… Continue reading this article “Why doesn’t my plant flower? Part 1”

Eggplants getting their buzz on

eggplantflower

I was checking my eggplants today, and watching the bumble bees getting busy with the large purple flowers. As they flew in, buzzing away, they landed on the flower and kept buzzing — but the note changed, dropping in pitch. The bumble bee hummed away for a while, then flew off to the next flower.

I was watching buzz pollination at work. Egg plants, and a lot of other flowers, don’t leave their pollen hanging out in the open where any ant or fly that happens by could eat it.… Continue reading this article “Eggplants getting their buzz on”

Observations regarding you-pick blueberries…

We just finished up with our 8th season of welcoming you-pickers to our back yard, which happens to include three acres of northern highbush blueberries. This has been an interesting venture – helps pay for our farm, obviously, but also presents an opportunity to connect with the “general public” outside of academia [that probably wouldn’t happen otherwise, considering we are both introverts]. Ninety-nine-point-nine percent of the folks that take the trouble to come to a you-pick are fabulous, functional human beings.… Continue reading this article “Observations regarding you-pick blueberries…”

Odie

One of the coolest plants you’ll ever see is the titan arum. It varies quite a bit in height, but this one, named Odie, measured just a little over five feet tall. This amazing corm bloomed at the UNC Charlotte Botanical Gardens last week. Unfortunately the bloom only lasted for about two days, and during that time the area around it smelled just like roadkill. We are now waiting to see whether a fertilization attempt was successful.… Continue reading this article “Odie”
