Lomatium piperi is a compact native wildflower that forms low, spreading clumps with delicate, finely divided foliage. It produces small clusters of yellow flowers from March through May, followed by a summer dormancy period. This drought-tolerant perennial thrives in sunny locations and requires minimal water once established.

Works well in: backyard only.
