Cerastium – Snow-in-Summer, Mouse-ear Chickweed, Perennials Guide to Planting Flowers


Snow-in-Summer is surely a very descriptive name for this low growing, white flowered and silvery foliaged plant. There are myriads of small white flowers produced in June from a dense mat of growth. Cerastium tomentosum is the common species and grows about 6 inches high. C. Biebersteinii is very similar but grows a little taller and has larger flowers. C. arvense is a green leaved species and stands the hot Summers better than the other two.

These plants are invaluable for the rockery or as an edging for beds and borders. They are also excellent to plant in dry, sunny places as a carpet covering for graves or steep banks. The leaves are as valuable as the flower.


The plants arc., very easily grown in any soil.


They are propagated by seeds, cuttings or divisions of the plant. The plant should be divided very early in the season, either with or without roots, and planted deeply in well firmed soil which sould be kept moist until roots have formed.
