Horticulture/Stellaria media

The common chickweed (Stellaria media) is a cool-season annual plant native to Europe. 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, and the seed pods explode when mature to disperse the seeds.

Description
Common chickweed is a low, mat-forming plant, present throughout the cool seasons and winter, but dying during hot weather. The roots are very fine, and the crown easily breaks away if pulled from very dry or frozen soils, allowing the plant to regrow.

Ecology
In both Europe and North America this plant is an invasive weed of gardens, fields, and disturbed grounds. Control is difficult due to the heavy seed sets.

Uses
The plant has uses in folk medicine; 17th century herbalist John Gerard recommended it as a remedy for mange. It can also be tolerated as a winter soil cover.
