Calochortus amabilis

Calochortus amabilis is found on open hillsides and in open woodlands in the Coast Ranges of California. 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. 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.
