The Mouse-Ear Chickweed (Cerastium fontanum) is a low-mounding subalpine plants bear small, white-woolly leaves and clusters of white flowers. The Cerastium tomentosum (Snow-in-summer), is a woolly, mat-forming perennial, more compact than the species. Give these care-free perennials average, well-drained soil, and full sun. Poorly drained soil will encourage fungal rots that blacken the foliage. Propagate by tip cuttings in summer or by division.
Mouse-ear Chickweed is well-adapted to growing among rocks. Plant it in walls or with spring bulbs, primroses (Primula spp.), and bellflowers (campanula spp.). The creeping mats are also attractive on sandy banks. It will also grow in containers.
