About

Phlox nivalis, the trailing phlox, is a mat-forming, evergreen perennial with long, trailing stems and small, hairy, lance-shaped leaves. Clusters of lilac-pink or occasionally white flowers are borne on short, upright stems in mid to late spring. A rewarding, low-growing phlox for a sunny, well-drained rock garden or wall top.
