Also known as Salvia yangii 'Lisslitt', this dwarf, shrub-like perennial produces profuse violet-blue flowers on compact spikes, with blooms that are larger and deeper in color than the species. Its lacy, silver-gray foliage is aromatic, adding both visual and sensory appeal to the garden.

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.
