Snow-in-Summer (Cerastium tomentosum): A Silver Carpet of White Blooms

Quick Facts

• Type: Evergreen perennial ground cover
• Zones: 1–24, 32–45
• Light: Full sun; partial shade in hot climates
• Water: Regular for fastest growth

Snow-in-summer forms a 6- to 8-inch-high mat of silvery gray foliage, smothered in small white flowers from late spring into early summer. It thrives in any well-drained soil, tolerates drought once established, but spreads fastest with regular water. Not long-lived—replant with divisions or cuttings when plantings look shabby after several seasons. Space 1 to 1½ feet apart. Avoid hot, humid Southern regions.
