Potentilla fruticosa
Shrubby cinquefoil is a tireless bloomer producing an endless stream of buttercup-yellow flowers from June to September. This compact shrub is hardy to the coldest zones and makes virtually no demands on the soil. The fine, compound leaflets give the plant an airy appearance. Ideal for low hedges and borders.
Plant in full sun in well-drained soil. Shrubby cinquefoil tolerates drought, wind, and poor soil without issue. Feeding is rarely needed. Water only during extreme drought. The plant is virtually disease-free.
Prune in early spring (March) by shortening the shrub by a third. Remove dead wood and crossing branches. Every few years, you can prune harder for rejuvenation. Avoid autumn pruning.
