The thing about being a horticulturist and a professor is that you’re always supposed to have the right answer. Which is to say, when I tell people not to use beer as a fertilizer, to avoid planting trees too deeply, and to reduce pesticide use, people take it for granted that I know what I’m talking about and that, if they don’t do what I say, there could very well be problems. But, as most of you know, growing plants is an art and a science, and sometimes plants decide to do things that are unexpected — plants are individuals after all, just like we are. … Continue reading this article “Being Wrong”

Friday’s puzzle solved
Here’s Friday’s photo without my edits:

As you can see, there are tell-tale globs of hot glue around the base of the bud on the right. Hap was correct – it’s yet another “cactus strawflower” whose cactus portion had disintegrated, leaving only the strawflower graft behind. But out of context it could easily be mistaken for a bulb of some sort. Let the buyer beware!
Friday fun, part 2
OK, enough tormenting of my fellow GP. On to today’s photo challenge.
Is it a miracle? Is it a resurrection plant? How do you explain these large buds emerging from the soil?

A disclaimer: a portion of this photo has been Photoshopped. I promise the altered area was not of plant material. Monday’s answer will include the untouched photo in bigger context
Friday fun, part 1
This posting is for Holly, who I am sure is desperately trying to finish her annual review. I feel your pain! And I’m going to add to it today.

The poinsettia in these photos is not from this Christmas, but from 2008. You can see it thriving happily in its office environment. I’m told by its caretaker Nick (a nongardener) that it has no bugs or other problems, and seems very happy. And it’s blooming, without the benefit of the extended night period. … Continue reading this article “Friday fun, part 1”
Friday’s puzzle solution
We have a winner! Brian correctly identified the windowed hood of a cobra plant (Darlingtonia) and its function in tormenting hapless insects. Here’s the entire picture:

Thanks to everyone who gave the puzzle a shot. Very imaginative guesses!
Friday Foto Fun!
I’m taking the easy way out this week, as I’ve got to get my annual review done by next Monday (and I haven’t even started it yet. Hah!). But over the weekend, let’s see if you can figure out (1) what this is, and (2) why it looks the way it does:

Monday’s photo will reveal all!
The Garden Professors Take a Holiday Break
Linda, Jeff, Bert, and Holly are taking a break. We shall return full-force January 4th. Note that there MAY be sporadic, interim postings if one of us gets significantly riled up. Subscribers to our RSS feed will be duly alerted.
My “greeting card” below was inspired by Jeff’s post on the insulating powers of snow. We here in the Blue Ridge Mountains of Virgina have about 14″ of insulation at the moment!
Finally, thank you to all our wonderful Garden Professors readers and commenters – you made our first six months so fun and rewarding!… Continue reading this article “The Garden Professors Take a Holiday Break”
Foliage fun flaunted!
Not much activity on the Friday quiz! It was a tricky one. Take a look at our photos in total:



As you can see, these aren’t plant “problems” in the strictest sense. (The “landscape” in question is a retail nursery.) They are cultivated anomalies – little mutations that have been discovered and propagated. There are several points to this exercise:
1) Be sure you know your plant material! Many peope mistakenly assume that plants such as these are diseased, pest-ridden, or lacking some nutrient and need to be “fixed.” … Continue reading this article “Foliage fun flaunted!”
Friday Foliage Fun!
Take a look at these three closeups of foliage from three different plants in a landscape in Washington state:


You’ve been asked to diagnose what’s going on in this landscape that would cause these foliar abnormalities. (I get photos emailed to me all the time asking these kinds of questions.) Bugs? Disease? Nutrient deficiencies? Environmental conditions? All of the above?
More photos and answers on Monday!
Is It Worth Anything?
Plant aficionados everywhere are constantly looking for something which they can patent and make a million bucks on — something like ‘Endless Summer’ hydrangea which captured the public’s attention — and their wallets. Many of the new plants we see today came from something called “branch sports” which are basically segments of a tree — like a branch — which has somehow mutated so that it offers something a little different than what the original tree did. … Continue reading this article “Is It Worth Anything?”
