About

Trifolium amoenum, known by the common names showy Indian clover and two-fork clover, is endemic to California, and is an endangered annual herb that subsists in grassland areas of the San Francisco Bay Area and the northern California Coast Ranges.

Where it grows

Edward Lee Greene collected the first recorded specimen of Trifolium amoenum in 1890 in Vacaville, California (in Solano County). Its historical range was from the western extreme of the Sacramento Valley in Solano County west and north to Marin and Sonoma Counties, where many sites were presumed extirpated by urban and agricultural development.
