The new garden under the front window after a frenzy of planting. A mulch of 3/4 inch or less gravel (one size up from pea gravel) is still needed, because uniform-sized gravel looks weird to me. I believe it was the late Duncan Lowe, in his book on growing alpine plants in troughs, who said it had a “funereal” look, and I agree. Gravel of different sizes looks better. (Incidentally, I hear that in the UK they call pea gravel “shingle”, but the phrase “mulched with shingle” conjures up quite a different image in a hail-prone region like this.)
The big green things are Hesperaloe campanulata, which is hardy in my garden, though I killed the last plant by constantly moving it from place to place. I got them from YuccaDo Nursery; they had two, so I bought both. This is what a plant hog does.
I decided to plant them now, to allow them to get used to Denver’s blistering sun, rather than at the “proper planting time for my area”, which, technically, is never. It will surely get cold and snow again before the first of June, but by then it could be too hot, dry, windy, and sunny, so I figured now was as good a time as any.
Also, and so exciting to me that I can scarcely contain myself, is this plant. I’ve been yearning for it for decades. Purshia glandulosa. I got it from Las Pilitas Nursery; they had two, so, well, I have two now.
Purshia glandulosa is the reason why the cliffrose, Cowania, was moved to Purshia, because the cliffrose hybridizes with P. glandulosa and also the bitterbrush, P. tridentata. There are some botanists who don’t agree with this; an interesting discussion can be found here.
I also yearn for the pink-flowered Purshia plicata, from Mexico; P. ericifolia, from Mexico and Texas, and P. pinkavae, from Arizona, the last two with yellow flowers like the rest, but these two plants will do for now.
I’ll try not to kill them.
