This past week I got to spend three days doing one of my favorite things; talking about conifers. Wednesday I was a last-minute guest lecturer for a landscape design class and Thursday and Friday I did my ‘Conifers for Connoisseurs’ talk for our MSU Extension ‘Plants of Distinction’ program. One of my favorite conifers and one I often recommend as a large specimen tree is Alaska yellow-cedar (the name I learned in Mr. Chance’s Botany class at Olympia High School) or Nootka false cypress (the usual common name for the tree in this part of the world). … Continue reading this article “A rose by any other name…”

Friday puzzle untangled
Well, either the puzzle was too easy or you guys are too smart! Deb, Christopher, Lori, Foy, Jim, and Hap go to the head of the class – it was, indeed, staking material left on way too long. Here’s a photo from over 10 years ago. I’m not sure this is the very same tree, but it’s from the same parking lot/torture chamber:
I “liberated” these trees with my handy wire-cutters (never leave home without them) shortly after taking the pictures. … Continue reading this article “Friday puzzle untangled”
Friday quiz…better late than never!
As you know, I wanted to get something intriguing for this week’s puzzler from the NW Flower and Garden Show. Alas, there was nothing that jumped out at me, so I’m digging into my photo archives.
Here is a recent photo from a parking lot tree. About four feet up the trunk, I found this interesting growth. No, I don’t know what the tree species is because (a) it wasn’t in leaf and (b) I’m a taxonomy klutz. … Continue reading this article “Friday quiz…better late than never!”
Friday quiz…yes it’s coming
As you might know, I’ve been at the NW Flower and Garden Show this past week, and yesterday I had two seminars to give. So I didn’t have a chance to post a quiz, and this morning I’m back over for a few hours before I’m done.
I’m hoping to find an interesting Garden Prof question topic at the show, so I’m taking the camera today. If I can’t, I have a backup. But I promise there will be a question up by today!
Plant Patents
I love patents. In fact, I once wrote a novel based on a patent — It was called Patent 22 — If you look this patent up you’ll just find a piece of paper from 1915 which says, essentially, that a search was made for the patent but that it couldn’t be found. No one wanted to publish it — and reading it now I do realize that it does need some serious work. Still, I think this little tidbit gives you a little bit of an idea about my interest in patents. … Continue reading this article “Plant Patents”
Water droplets and burned leaves, continued
A few weeks ago (January 20 – “Help, help, the sky is falling”) I started a discussion about an article appearing in the peer-reviewed journal New Phytologist. That posting focused on the methodology and results in the paper. Today let’s take a look at the authors’ underlying arguments (their introduction to the study) and their conclusions.
1) The authors’ premise is that “laymen and professionals alike commonly believe water drops on plants after rain or watering can cause leaf burn in sunshine.” … Continue reading this article “Water droplets and burned leaves, continued”
All Right, Linda; I’ll See Your Paraheliotropism and Raise You a Nyctinasty
Amicia zygomeris is a cute little herbaceous thing I picked up on a visit to Plant Delights nursery back in October. For $13, I wanted to be sure it survived the winter, so it’s been in our kitchen garden window, just waiting for spring.
Soon after putting it in the window, I had an “oh no, I’ve killed it” moment one evening. All the leaves were drooping, yet the soil was moist. The next morning, it seemed to be back to normal. … Continue reading this article “All Right, Linda; I’ll See Your Paraheliotropism and Raise You a Nyctinasty”
Checking up on FreezePruf
As winter continues to hold its icy grip over the middle of the country, our thoughts don’t stray too far from plants and cold. Recently one of the graduate students in our department, Nick Pershey, brought to my attention a new product called FreezePruf that claims to improve plant cold hardiness by up to 9 degrees F. Since a couple of degrees of improved cold tolerance can be a big deal (just ask a Florida citrus grower after a 29 deg.… Continue reading this article “Checking up on FreezePruf”
Friday puzzle answer(s)
Wow! What a lot of great brainstorming over the weekend! I would venture to say that The Garden Professors have the smartest students in the world.
On to the answer…or answers. First, the phenomenon. It’s called paraheliotropism – literally, a movement to protect (the leaves) from the sun (yes, Trena, it is a tropism!). This is the opposite of another phenomenon called heliotropism, or solar tracking. Sunflowers famously do this, as do a number of arctic species that collect solar warmth for the benefit of their pollinators. … Continue reading this article “Friday puzzle answer(s)”
