Commonly known as Indigofera or indigo, this deciduous shrub grows on streams and in woodlands in its native south central 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 wide as it is tall, 4-6 feet, it's leaves are grey green of 4-6 inch pinnate leaflets, but the fall color is not distinguished. The flowering time, however, is extended from May to September. The pea-shaped blooms of pink to rose to lilac are held in narrow racemes of 2-5 inches and are followed by dark purple seed pods. Insects, Diseases and Other Plant Problems:
