Common chickweed is an annual, low-growing herb native to Europe. Stems are decumbent, to 19.7 in. (50 cm) long with a longitudinal line of hairs. Leaves are opposite, oval, to 0.8 in. (2 cm) long and pointed at the tip. Older leaves are petiolate. Flowering occurs in early spring when small, white flowers develop in the leaf axils or in terminal clusters. Flowers have 5 cleft petals, therefore appearing that there are 10. Fruits are very small and are covered by extremely hairy calyces. Common chickweed occurs in shady, moist locations and can commonly threaten habitats on rocky seeps. |
