Calochortus amabilis Purdy is found on open hillsides and in open woodlands in the Coast Ranges of California. This species was featured in Mariposa,Volume 4,#4. It has yellow globe flowers and is known as Diogenes' Lantern. Its closest relative is the more robust Calochortus pulchellus which is endemic to Mount Diablo with greenish bracts. The bracts on Calochortus amabilis are pure yellow. The Jepson Herbarium Calochortus key describes the leaves of Calochortus pulchellus as green and those of Calochortus amabilis as more or less glaucous. This species can be grown in semi-shade or full sun. In full sun, sometimes the leaves take on a purplish appearance. Except for sunlight, treat this species the same as Calochortus albus.
