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.

[1] A member of the genus Indigofera, its family is Fabaceae[2] and is used primarily for decorative purposes,[3] though it has also been used to make indigo-colored dye.

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.

It is somewhat heat and drought tolerant, but benefits from afternoon shade in hot, humid environments.
