Cerastium is a genus of annual, winter annual, or perennial plants belonging to the family Caryophyllaceae. They are commonly called mouse-ear chickweed. Species are found nearly worldwide but the greatest concentration is in the northern temperate regions. There are about 200 species. A number are common weeds in fields and on disturbed ground.

Cerastium species are used as food plants by the larvae of some Lepidoptera species including Coleophora chalcogrammella (which feeds exclusively on Cerastium arvense) and Coleophora striatipennella (which has been recorded on Cerastium fontanum).

Cerastium Tomentosum (UK Snow In Summer) Great ground cover for those 'difficult' areas. Likes full sun and free draining soil though I have had great success in full shade and damp ground. One of the easiest plants to propagate. I just pull off a lump,with or without roots, dig a slit, poke it in, water well and it invariably roots rapidly and flowers the following year. Can be invasive.
