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.
