Last updated
Potentilla fruticosa (Rosaceae), now often listed as Dasiphora fruticosa, is a deciduous shrub native to the Northern Hemisphere across North America, Europe, and Asia. It grows 1 to 4 feet tall with a compact, rounded habit and small, pinnately compound leaves. Buttercup-like yellow flowers (about 1 inch across) appear continuously from early summer through fall.
Shrubby cinquefoil thrives in full sun on well-drained soil and tolerates poor soils, drought, cold, and alkaline conditions. It is one of the longest-blooming deciduous shrubs. Many cultivars are available in flower colors ranging from white to yellow to orange to pink. The pink and orange cultivars may fade in intense heat. No serious pest or disease problems are documented. Hardy in Zones 3a to 8b.
