  A wonderful hybrid from North Carolina Botanical Garden, its greyish violet pea-like flowers form in long spikes that are supported by near-black stems. This false indigo is perfect for a well-drained border or a dry, sunny bank as it will become drought tolerant once well established. Resist the temptation to cut the plant back in autumn as the seed-pods and slender stems look wonderful frosted in the winter garden.
  
  
• Garden care: Keep new plants well watered. Lift and divide large colonies in early spring.
