Salvia canescens var. daghestanica

Salvia daghestanica likes a hot, sunny position in any well-drained soil. Grow it just like lavender -- it doesn't want to be wet at the roots or heavily watered. When planting, mixing in a ample helping of coarse grit and planting it on a slightly raised mound of soil to aid drainage should help it survive a wet winter. Another idea is to mulch it with two to three inches of sand when planting. A native to the Caucasus Mountains near the Black Sea. In early summer, the low, tight rosettes of textured foliage are very white and create a superb backdrop to the showy 8 to 10-inch tall spikes of large clear-blue flowers. Besides planting in a rock garden it can be used in the perennial border as an edging plant and as a companion around taller plants. USDA Zones 5 - 8.
