Caulanthus glaucus is a species of flowering plant in the family Brassicaceae known by the common names glaucous wild cabbage, bigleaf wildcabbage, and limestone jewelflower.[1] [2]
It is native to southern Nevada and adjacent parts of eastern California and Mojave Desert sky islands, where it grows in open, rocky habitat in the desert mountains.
Caulanthus glaucus is a perennial herb producing a slender, branching stem from a woody caudex.
The largest of the leaves appear in a cluster at the base of the plant, and are oblong or oval and up to 10 centimeters long. Smaller, lance-shaped leaves appear higher up on the stem.
The flower has a coat of thick green sepals over narrow yellowish or purplish petals. The fruit is a long, thin silique which may approach 15 centimeters in length.
