Perovskia atripl. 'Blue Spire'

Perovskia "Blue Spire", also called blue spirea, is a remarkable, deciduous shrub, with an upright habit and beautiful, lavender to blue flowers, in narrow flasks of tubular flowers. The leaves are gray-green, coarsely serrated and fragrant when crushed. Perovskia prefers a sunny position in a pH-neutral to calcareous, well-drained soil. It requires a firm pruning every autumn to within 30 cm from the ground and a winter protective layer of leaves. Blue spirea is moderately to fairly hardy, disease and drought resistant, well tolerant to sea wind, pest free and can also handle some air pollution. The plant will need some support in full summer.
