Stellaria

Stellaria is a genus of about 190 species of flowering plants in the family Caryophyllaceae, with a cosmopolitan distribution. Common names include starwort, stitchwort and chickweed.

Description
Stellaria species are relatively small herbs with simple opposite leaves. It produces small flowers with 5 sepals and 5 white petals each usually deeply cleft, or none at all, all free. Stamens 10 or fewer.

Uses
Some species, including Stellaria media which is widely distributed throughout the Northern Hemisphere, are used as leaf vegetables, often raw in salads. This is a favored food of finches and many other seed-eating birds.

Chickweeds are used as food plants by the larvae of some Lepidoptera species including angle shades, heart and dart, riband wave, setaceous Hebrew character and the Coleophora case-bearers C. coenosipennella (feeds exclusively on Stellaria species), C. lineolea (recorded on S. graminea), C. lithargyrinella (recorded on S. holostea), C. solitariella (feeds exclusively on S. holostea) and C. striatipennella.

Several closely related plants referred to as chickweed, but which lack the culinary properties of plants in the genus Stellaria, include members of the genus Cerastium, of similar appearance to Stellaria and also in the (Caryophyllaceae).
