Chinese Indigo is one of our favorite perennials/subshrubs. Arising from the ground in late spring the arching stems to 3′ support 6″ long pendant pale rose pink flowers for months and months. No intervention needed from the gardener. In time it suckers to form 4′ wide patches. Regular water to establish in average to rich, well drained soil. Full sun. Freezes completely to the ground in winter- cut back defunct stems from the previous year in early spring. When it does emerge its a very quick trip to up and blooming. Incredibly drought tolerant when established but light consistent watering seems to encourage new flowers- as it grows it blooms so you want to keep it growing. Incredibly elegant but tough plant that asks for so little but gives so much.
