Growing and Maintenance Tips:

Perovskia is drought-tolerant and dislikes winter wetness, growing best in an average to dry, well-drained soil, in full sun. In the fall, spent flower spikes can be pruned off for a tidier appearance. Note: Perovskia should not be pruned too far back until new growth emerges in the spring, and once the new growth appears, prune back to no lower than 30 cm.
