Valuable groundcover, this clump-forming perennial has handsome foliage, which may have purple-brown blotches and in late spring and early summer, maroon or near black flowers with white centres.
Geranium phaeum, and its cultivars, prefer reliably moist to damp soils with some shade. When planting, incorporate a scoop of well-rotted compost into the planting hole and water in well. Once established, in midsummer rejuvenate plants that are beginning to look jaded, by removing old flowered stems and leaves. After a couple of seasons, lift and divide large clumps in spring to maintain plant health and vigour.
