Dryas octopetala

White Mountain Avens is native to the mountains of North America, usually growing in gravel or sandy soil. It forms a low mat of small, glossy evergreen leaves, the woody stems rooting along the ground where they touch. Small starry white flowers appear in late spring followed by feathery seedheads in the summer. At home in a well-drained rock garden, also useful for edging pathways, in rock walls or growing between paving stones. Plants are not usually happy about being divided. Self-rooted stems may be moved to a new site in the spring.
