Description
One of my favourite perennials for almost any colour border, with rich, deep indigo-blue, pea-like flowers. It flowers all summer and then, with flowers picked or deadheaded, it gives you excellent silvery foliage through the autumn and well into November. This picks well too.
Care Tips
Deadhead to prolong flowering but leave some at the end of summer to develop seed heads for winter decoration. Drought-resistant once established. Prefers not to be disturbed but large clumps may be divided in spring.
