Wide sloping valley bottom, heavily infested with weedy naturalized grasses that are encroaching on patches of native vegetation. Low-lying regions which retain water longer into the season seem to be more resilient to competition from non-native grasses. Soil clay, within matrix of chunks of basalt. Locally uncommon but regionally abundant perennial herbs from subglobose, deep-seated tubers surmounted by an elongate rootstock bearing usually 1-3 stems. Plants purple-tinged throughout aerial parts, but not on leaf blades. Leaves glaucous grey-green, flowers bright white, with purple anthers and stylopodia. Associates: Lomatium gormanii, Tauschia hooveri, Crocidium, Poa spp. Lomatium DNA Voucher; Emma George 2011. Phenology: Vegetative.
