DESCRIPTION:
Common chickweed, a winter annual, is a low-growing, succulent weed that often spreads out in extensive mats. It may survive the summer months in shady, cool areas that offer sufficient moisture. Along the California coast, it can survive year-round. Seed leaves have prominent midveins and are about four times as long as broad, tapering to a point at the tip. True leaves are broader, opposite, and yellow green. Chickweed mats may cover a large area. Stems are trailing, weak, and slender, with a line of hairs down the side. Mature leaves are ovate and opposite on the stem. Most leaves are attached to the stem by hairy petioles, but some upper leaves lack petioles. Flowers are small but showy with five deeply cut white petals.

See UC IPM's Chickweeds Pest Note for more information.
