USDA Symbol: COER

USDA Native Status: L48 (N), PR (N), VI (N)

The soft, jointed stems of this perennial grow upright only if supported by other plants. Usually they lie on the ground and grow up to 3 ft. long. The ephemeral flowers, about 1 in. across, have two larger, showy, blue petals and one much smaller white petal. Flowers with 2 large, ear-like, blue petals and one smaller petal bloom in small clusters, in a bract, at the top of several erect branches. They only bloom for a day, but there are several buds on a plant that open 3-4 days apart. The principal leaves are linear to somewhat lance-shaped.

This is a highly variable species. The Spanish name means "herb of the (cooked) chicken."
