About Yerba Mansa (Anemopsis californica) Yerba mansa or lizard tail, is a perennial flowering plant within the family Saururaceae. It is the only species in the monotypic genus Anemopsis. It is native to southwestern North America. In early spring numerous tiny white flowers are borne on a cone which is surrounded by 4-9 large white spoon-shaped bracts that look like petals. As it matures, the visible part of the plant develops red stains, eventually turning bright red in the fall. Yerba mansa means "calming herb" in Spanish (yerba = "herb"; mansa = "calm or tranquil").

Yerba Mansa requires moist soil, so best to plant in streambeds, seeps or other damp areas. It goes dormant and basically disappears from late summer to early winter, and re-sprouts from the roots in late winter. It produces beautiful white flowers in the early spring that remain on the plant until it starts to go dormant in late summer. It will often spread out like a carpet throughout the damper soil, and choke out any other plants in the area, and in particular while it's blooming, it's quite beautiful.
