Surviving the desert with beauty and efficiency

I’m away this week for an out-of-state seminar and a little annual leave.   Some of my favorite places to visit this time of year are the high deserts of California.  Today we hiked to Horse Thief Creek, a relatively easy trail in the Santa Rosa Wilderness.  It’s the perfect time of year to see the high desert in bloom, especially with last winter’s substantial rainfall.

In graduate school I became interested in environmental stress physiology, and I still am entranced by the plant kingdom’s ability to overcome nearly every environmental extreme on earth. Continue reading this article “Surviving the desert with beauty and efficiency”

Devious dandelions

As Austrian reader Johannes explained, the difference in dandelion flower height is due to herbivory – in this case from a lawnmower.  Dandelions are quite adaptable to variable environments (the phenotypic plasticity Johannes also mentioned) and flower heights will increase or decrease depending on these variables. This ensures that the flowers will be accessible to pollinators, yet not decapitated by lawnmowers.  It’s just one of the fascinating traits that make weeds successful!

 

A Taraxacum teaser

It’s spring and the dandelions are happy to see you!  I’ve taken photos of two groups of dandelions just footsteps away from one another. The populations are both in full sun, with similar types of soil and water availability. You’ll note that one group has very short flower stalks, while the second has longer stalks:

So what’s responsible for the difference in flower stalk length?  And for extra credit, what’s the scientific term for the phenomenon?… Continue reading this article “A Taraxacum teaser”

Edgeworthia!

Some of my favorite plants are those that “do something” when little else is.
Do we really need more June-flowering perennials? No!
Well, yes. Never mind.

Edgeworthia chrysantha – “Paperbush” is the common name – is a deciduous suckering shrub , native to China. It usually maxes out around 4′ to 5′ tall and as wide.  The large, matte bluish-green leaves resemble those of Magnolia virginia in shape and are also a bit silvery on the underside. … Continue reading this article “Edgeworthia!”

I’m Saving Myself for Pollination

Let’s take a very brief respite from the socio-religious implications of science, soil testing, and compost tea to ponder a more lighthearted topic. I need a bit of a morale-boost.

You: “O.K. Holly, Spring’s allegedly coming…how about a closer look at some wildflowers?”

Me: “Done!” (fingers snapping)

For a short time in March, forest floors across Eastern North America can be absolutely littered with a multitude of sparkling white flowers.  This very cool little plant, Sanguinaria canadensis, is one of the first wildflowers to emerge in the spring and colonizes deciduous and mixed woodlands.… Continue reading this article “I’m Saving Myself for Pollination”

My summer vacation

I’m following Holly’s lead and slipping into fantasyland today.  Though this part of the country has no snow, it is a typical cool, misty and gray winter morning in Seattle.  So I’m going to a happy place and reminiscing about my summer vacation to Sechelt, British Columbia.

Sechelt (pronounced like “seashell” with a “t” at the end) is a lovely place full of wonderful people (and great gardeners!), but I’m going to focus on the coastal rock gardens at Smuggler’s Cove Marine Provincial Park. … Continue reading this article “My summer vacation”

The Glories of The Winter Greenhouse

I’m a Southerner. With a capital “S”.  Which is why I am Suffering, with another capital “S”. Here in the Blue Ridge mountains of western Virginia, we have officially surpassed Anchorage and Denver in total snowfall for the season. Today’s batch adds up to 24″ on the ground at our farm.


Blueberries in the snow. If one more person says “Probably good for all the insect problems,” I’m going to get violent.

The chickens are not happy.… Continue reading this article “The Glories of The Winter Greenhouse”

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”

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”

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)”
