Aesculus californica

The showy floral spikes of the California Buckeye will give way to large green pods, which in turn produce the shiny brown seeds--sometimes called horse chestnuts—that give the plant its name. Though all parts are toxic, the nut meal can be made edible by leaching, and was a food used by indigenous Californians. This winter-deciduous small tree is found in the mountains and foothills of central California.
