It is native to western North America, including the Northwestern United States and California. It grows in moist wooded and forested areas, most commonly in montane forests between 1,200–3,000 metres (3,900–9,800 ft).[2][3]

The green leaves have blades up to 20 centimeters long which are divided into toothed and irregularly cut leaflets. The blade is borne on a long petiole.[4][5]
The inflorescence is a compound umbel of many tiny yellowish flowers at the tip of a stemlike peduncle. The fruit is elongated and narrow, up to 2.2 centimeters long.[4][5]
