Chickweed

Chickweed (Stellaria media), one of the commonest English weeds, a small annual belonging to the Caryophyllaceae, with five sepals, five or fewer two-cleft white petals of small size, ten stamens, three styles and a six-valved capsule, but readily recognised by a single line of small hairs along the stem, changing from one side to the other at each pair of leaves. It is collected as a food for cage-birds. It is one of the most widely diffused of flowering plants.
