Commonly known as Chinese indigo, this deciduous shrub grows on streams and in woodlands in its native Japan and China and is suited to average well-drained neutral to slightly alkaline soil and medium moisture. It can be sun, but in a hot, humid atmosphere, it benefits from afternoon shade. It can also suffer damage to the branch tips in a harsh winter. As it flowers on new growth, it is best to prune to close to the ground or to live growth very early in the spring or even late winter. This indigo is spreading at 3-4 feet wide and 1-2 1/2 feet tall. It's leaves are dark green of 8 inch pinnate leaflets and can be used for indigo dye. The flowering time is concentrated June and July and may be extended to September in sporadic blooms. The pea-shaped pink blooms are held in narrow racemes of 4-8 inches.
