Description

Chinese indigo is a deciduous shrub in the bean family (Fabaceae) native to Japan and China and can be found growing along streams and in woodlands. The specific epithet means decorative.

Grow Chinese indigo in average, well-drained neutral to slightly alkaline soil and medium to low moisture in full sun. In hot, humid climates it benefits from afternoon shade. Once established, it is somewhat drought-tolerant. It blooms on new wood, so prune in late winter. In colder climates, it will suffer branch tip damage or die to the ground to return in spring. The shrub will grow up to 2. 5 feet tall and spread 4 feet wide.

The 8 inch long compuond leavs of Chinese indigo are dark green and can be used for indigo dye.  The pea-shaped pink to lilac and rarely white blooms are held in narrow racemes of 4-8 inches and occur in June to July with sporadic reblooming into fall.

Use this shrub in the foundation, shrub borders, on banks and slopes or in cottage and pollinator gardens.
