Blooming profusely in late spring and early summer, Cerastium tomentosum (Snow-In-Summer) is a low-growing, short-lived perennial that forms a dense mat of silvery-gray foliage dotted with star-like, pristine white flowers with notched petals. Evergreen, it spreads quickly by reseeding itself and makes a great ground cover for sunny areas.
- Winter hardy, this low-growing perennial grows only 6-12 in. tall (15-30 cm) and spreads 6-18 in. (15-45 cm).
- Best in full sun in dry, sandy, well-drained soils. Tolerates a wide range of soils, but good drainage is essential. Grows well in cool summer climates and is intolerant of high summer heat and humidity. Drought tolerant.
- Great choice for rock gardens, edging, ground cover or containers. Lovely on a stone wall for a cascading effect. Deer resistant!
- Plants will self-seed in the garden if spent blooms are not removed.
- Best to shear off flower stems after bloom in order to prevent self-seeding and maintain a tidy habit.
- Easily divided in spring or fall.
