Silene alpestris ‘Starry Dreams’

A useful rock garden or alpine perennial, this flowers during the summer when so many other alpines have already finished. It forms a low, trailing mound or tuft of deep green leaves, bearing short stems with starry, upward facing, white flowers over a long season. Prefers a gritty, well-drained soil but dislikes being extremely dry. Excellent growing between rocks or in walls and planters. Evergreen. Most likely will prove hardy to Zone 4 or possibly colder.
