Why You’ll Love It

Cerastium ‘Snow in Summer’ is a much-loved groundcover perennial, valued for its carpets of silvery foliage and masses of crisp white flowers that appear in late spring. The low-growing, spreading habit makes it ideal for edging paths, spilling over walls, rockeries, and filling sunny gaps in garden beds.

Planting & Care Tips

• Plant in full sun for best foliage colour and flowering

• Prefers well-drained soil; ideal for rockeries and slopes

• Water during establishment, then sparingly once established

• Shear back after flowering to maintain a neat, compact form

• Avoid heavy, waterlogged soils to prevent dieback
