Stellaria media
''Stellaria media'', chickweed, is a cool-season annual plant native to Europe, but naturalized in many parts of North America. It is used as a cooling herbal remedy, and grown as a vegetable crop and ground cover for both human consumption and poultry. It is sometimes called common chickweed to distinguish it from other plants called chickweed. Other common names include chickenwort, craches, maruns, winterweed. The plant germinates in fall or late winter, then forms large mats of foliage. Flowers are small and white, followed quickly by the seed pods. This plant flowers and sets seed at the same time.
== Distribution and identification ==
''Stellaria media'' is widespread in North America and Europe. There are several closely related plants referred to as chickweed, but which lack the culinary properties of plants in the genus ''Stellaria.'' Plants in the genus ''Cerastium'' are very similar in appearance to ''Stellaria'' and are in the same family (Carophyllaceae). ''Stellaria media'' can be easily distinguished from all other members of this family by examining the stems. ''Stellaria'' has fine hairs on only one side of the stem in a single band and on the sepals.〔Parnell, J. and Curtis, T. 2012. ''Webb's An Irish Flora.'' Cork University Press. ISBN 978-185918-4783〕 Other members of the family Carophyllaceae which resemble ''Stellaria'' have hairs uniformly covering the entire stem. It usually has 3 stamens〔 other references indicate 5 stamens〔Martin, K. 1965. ''The Concise British Flora in Colour''. George Rainbird Ltd〕 and 3 - 8 in other references.〔Clapham, A.R., Tutin, T.G. and Warburg, E.F. 1968. ''Excursion Flora of the British Isles.'' Cambridge Press. ISBN 0-521-04656-4〕
