Perovskia atriplicifolia

Shrub-like plant developing a woody character with silvery aromatic leaves.  Offers great mid – late season show of lavender-blue flower spikes which persist for six weeks or more from July-Sept.  Best results are obtained in full sun and well-drained soil.  Heat and drought tolerant.  Grows 3-4′ high by 2-4′ wide.  Plants respond to a hard cutting-back in late spring and another shearing in early summer to produce sturdy dense plants.
