  • Description

  • Notes

Masses of snow white flowers cover this plant from late spring to early summer. Fine textured foliage is silvery grey. After flowering, shear back plant to encourage new foliage and for a tidy appearance. Over-head watering may cause the plant to "melt-out" in the center; over-watering, in general, causes the plant to die out over time. An attractive filler among other plants and rocks, and nice ground cover for areas that receive little foot traffic. Plant at edges of walks to soften paths. I saw a lovely planting where cerastium was used to represent water in a "dry creek" design-Brilliant. Grows 4 to 5 inches tall and 15 to 18 inches wide.
Grow in full to half sun in well drained soil. Shear back after flowering for a tidier appearance; in large areas, use a lawn mower or trimmer. Deer resistant.
