Perovskia are graceful aromatic shrubs with an open habit. Long spikes of silvery-blue flowers accent its complementary silver-gray foliage. Flowers almost two months from the summer into the fall. Shrub-size, semi-woody plants for full sun. Drought tolerant. Avoid too moist (wet feet).

Prefers somewhat dry soil with good drainage. Can be divided every 4-6 years in spring or fall. Offsets from side of clump can be dug and transplanted. Should not be cut back hard in the fall, leaving some stem buds for next year's growth. Clean up old foliage and stems in spring.
