Adobe yampah is a California native perennial found in the Tehama, south Coast Ranges, and western Transverse Ranges on grassy slopes and serpentine outcrops at elevations of 300 to 1,800 meters. Flowering from April to June, this plant produces small white flowers in delicate umbels with 5 to 7 rays spreading in an open, ascending pattern. Growing 3.5 to 7.5 decimeters tall with tuberous roots clustered in groups of 2 to 4, it develops distinctive finely divided leaves. Its basal leaves are broadly ovate, twice-pinnate with extremely narrow leaflets less than one millimeter wide and up to 8 centimeters long, creating a feathery, delicate appearance. The fruit is an oblong structure 5 to 8 millimeters long with thread-like ribs and 3 to 4 oil tubes between each rib.
