Snow-in-summer (Cerastium tomentosum)
Quick facts and care essentials
• Evergreen perennial
• Zones 1-24, 32-45
• Full sun; partial shade in hot climates
• Regular water for fastest growth
Reliable everywhere except in the hot, humid South, snow-in-summer grows 6 to 8 inches high, bearing silvery gray foliage and masses of small, snow white flowers from late spring into early summer. It takes any soil as long as drainage is good; it tolerates drought once established, but spreads fastest with regular water. It is not long-lived. When plantings start to look shabby after several seasons, replant with divisions or cutting-grown plants. Space 1 to 1 1/2 feet apart.
