Excellent plant that provides interest from May right through to late summer if you dead head. Deep pinkish purple stems are tightly packed with bracts of the same colour that produce deep blue flowers. Does best in sunny spot on well drained soil and will be drought tolerant once established. Constantly hums with bees busy at work too.
A real good doer that was voted Perennial Plant of the Year in the USA in 1997 and holds an AGM
