A spreading annual herb. It grows 50-100 cm high. The stems are angled and grooved. The leaves simple and alternate and can have lobes or teeth. There are spreading hairs on the stems. The flowers are in small groups and are drooping. They are in the axils of leaves. The flowers are white, star shaped and 16 mm across. The fruit are green but turn black and 8 mm across. There are many seeds.
