Eriogonum truncatum
Also called Contra Costa Buckwheat, Mount Diablo Buckwheat
Mt. Diablo buckwheat is a small annual wildflower with pink, maroon-lined blooms, known only from Mount Diablo in Contra Costa County, California. It was thought extinct from 1936 until rediscovery in 2005, so it is grown mainly from collected seed for conservation.
Eriogonum truncatum, the Mount Diablo buckwheat, is a small pink wildflower, believed to have been extinct since 1936 until its rediscovery in 2005. The species is only known to live on Mount Diablo in Contra Costa County, northern California.
It has been found on the edge of chaparral but may be a refugee there, squeezed out of more open areas by exotics. Since its rediscovery seeds have been collected for controlled propagation and preservation.
