ornamental jewelweed

Geraniales > Balsaminaceae > Impatiens glandulifera Royle

Ornamental jewelweed is a succulent annual than can be 3-10 ft. (0.9-3 m) tall. The stems are purple-tinged and hollow with opposite or whorled, elliptical leaves. Leaves are simple, serrate and 6 in. (15.2 cm) long. Flowering occurs from June to October when white, irregular, solitary flowers appear on axillary stalks. Fruits are five chambered capsules that, when mature, explode when touched. Ornamental jewelweed is native to India and occurs in areas with high soil moisture, such as riparian areas. Plants are partially shade tolerant.
