Sedum valens

Sedum valens
Idaho stonecrop

Common name Idaho stonecrop
Family crassulaceae
Life cycle biennial (Z5)
Flowers yellow
Cultural notes drought-tolerant

Recently discovered species, found in the Salmon River Canyon in Central Idaho. It differs from similar species in the large number of glaucous gray-green leaves forming good-sized rosettes. Very slow growing from seed: the picture below (taken in early July) was the largest of the four surviving seedlings in my first attempt at growing this species from seed (started in late January); it is perhaps 3/8" in diameter. And it didn't survive through the summer. The next year, plantlets developed slightly faster: the photo at right was taken in late April, and the photo at top in mid May, after setting the seedling out into a hypertufa trough. It is gaining a subtly pink coloration to the center of its rosette.

Sedum valens
Stayed tiny and eventually perished in our first attempt to grow it

We left this plant behind in our Pennsylvania garden (and wish it well); we don't grow it in Houston.

Seed for this plant is included on my seed trade list
