Foamflowers produce masses of fluffy, white or pink flower spikes, in early spring or summer. These perennials are also valued for their evergreen leaves, which are green, and often marked with brown blotches. Some spread by runners and make good ground cover, while others are clump-forming.
There are up to five species, originating from the woodlands of North America and East Asia. A lot of breeding work is being carried out in the USA and, as a result, a lot of varieties seen in gardens are modern hybrids.
They perform best in a moist, humus-rich soil in shade, but many will tolerate drier soils once established.
