Chinese Indigo

Indigofera decora, commonly known as summer wisteria, is a species of shrub native to China and Japan that has since been introduced to Australia and Sri Lanka. A member of the genus Indigofera, its family is Fabaceae and is used primarily for decorative purposes, though it has also been used to make indigo-colored dye.

I. decora is a deciduous, spreading shrub. It often grows 1–2.5 feet tall and 3-4 feet wide. It features compound, pinnate leaves up to 8 inches long with 7-13 elliptic, dark green leaflets. In the summer, it produces axillary racemes of light pink or purple pea-like flowers. Each raceme may boast twenty to forty flowers, and the calyxes have broadly triangular lobes.
