Snow-in-Summer (Cerastium tomentosum)

Cerastium tomentosum, known as snow-in-summer, is a short-lived, low-growing, mat-forming perennial which is typically massed in sunny locations as a ground cover. In late spring, flower stems rise above the foliage mat (typically to 8-12”) carrying clusters (cymes) of white blooms which form a snow-like carpet (hence the common name).


Best grown in dry, sandy, well-drained soils in full sun. Tolerates a somewhat wide range of soils except poorly-drained ones which inevitably lead to root rot. Grows well in cool summer climates. Plants are winter hardy to USDA Zone 2. Intolerant of the high summer heat and humidity of the deep South.
