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 autumn 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.
Stellaria media is widespread in North America, Europe and Asia. 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 (Caryophyllaceae). 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. Other members of the family Caryophyllaceae which resemble Stellaria have hairs uniformly covering the entire stem. It usually has 3 stamens other references indicate 5 stamens and 3 - 8 in other references.
The larvae of the European moth yellow shell (Camptogramma bilineata), of North American moths pale-banded dart (Agnorisma badinodis) or dusky cutworm (Agrotis venerabilis) or North American butterfly dainty sulphur (Nathalis iole) all feed on chickweed.
In both Europe and North America this plant is common in gardens, fields, and disturbed grounds. Control is difficult due to the heavy seed sets. Common chickweed is very competitive with small grains, and can produce up to 80% yield losses among barley.
