Chaerophyllum tainturieri

This plant is a winter or spring annual about ½–1½' tall. Several branching stems develop from the base of the plant; they often sprawl across the ground or lean on adjacent vegetation for support. The stems are light green to purplish green, more or less hairy, and shiny; the hairs occur in lines along the stems or in tufts where the stems branch. The blades of the alternate leaves are up to 4" long and 2" across; they are medium green, hairless to mostly hairless, double-pinnate, and triangular-lanceolate in shape. The pinnatifid leaflets are shallowly to deeply cleft and their tips are obtuse. The petioles of the lower leaves are about as long as the blades, while the upper leaves have short petioles or they are nearly sessile. A membranous sheath wraps around the base of each petiole.
