Vernacular names

Hesperochiron is a small genus of plants in the waterleaf family containing two species native to western North America. These are thick-rooted perennial herbs growing in squat patches at ground level and producing bluish-white flowers with yellow throats. They grow in wet areas such as seepy meadows.

The species are generally similar in appearance, with oblong green leaves up to 7 or 8 centimeters long and 2 to 3 wide, often coated with tiny hairs. Hesperochiron californicus, the California hesperochiron, produces slightly larger flowers than the dwarf hesperochiron, Hesperochiron pumilus.
