A Few Film Photos Taken in the Alpine Garden at the Denver Botanic

The large inflorescence in the background of this photo belongs to Agave parryi, an agave that can be hardy to -18C (according to “High and Dry: Gardening with Cold-Hardy Dryland Plants” by Robert Nold), depending on the growing conditions. Recently, I have been learning about some of the hardier agaves and was pleased to see a few at the Denver Botanic Gardens that were not only over-wintered outdoors, but in bloom.

The Aliens Have Landed

Stemless Thistle (Onopordum acaulon), hands down the most memorable plant of our trip to Denver.

I REALLY want to grow this one in my own garden and am now looking for some seeds to purchase.* I have a soft spot for thistles, so much so that I won’t pull the wild growing ones when they are seedlings, only to suffer the consequences later.

* Some places have declared this plant an invasive pest. Worth looking into before adding it to your garden.

Chance Xeriscaping

This image functions as a good demonstration of just how dry gardening is in Denver without the benefit of a hose. This landscape is nothing more than a random scattering of common mullein (Verbascum thapsus) with a few hot pink-flowered hollyhocks and dry land grasses thrown in. I’m not even sure it qualifies as a garden in the traditional meaning of the word since it looked to be completely untended and the product of a few resilient volunteer plants.

And yet it works. I’m sorry I didn’t capture it with the digital camera, but the silvery verbascum alongside tall, hot pink hollyhocks really made a stand-out pair. I was intrigued enough to ask our friend to stop the car and let me out so that I could take a few (or several) photos with all four of the cameras that I had in tow. I didn’t make that request for any of the “proper” gardens we saw. But then again, I am a sucker for the soft, statuesque grace of verbascum.
