Perovskia (Russian Sage)
Russian Sage provides long-lasting color in late summer with its spiky blue flowers. It is also a bee magnet. A very easy-to-grow perennial given the proper conditions (see below) and very tough and drought-tolerant once established. The plant name comes from Russian general V. A. Perovsky (1794-1857).
Common Name: Russian Sage

Native Range: Afghanistan, Pakistan, Asia
Type of Plant: Perennial
Hardiness Zone: 4 (-20 -30 degrees)

Size: Different cultivars are available with the tallest varieties reaching 5 feet or more. Recent introductions, such as ‘Little Spire’, grow 2-3 feet. Plants are generally very bushy and need space to spread. They dislike being crowded.
Growing conditions: Well-drained, sandy or loamy soil is best. Plant in full sun (at least 5-6 hours of sun). Drainage is essential during the winter months as wet soils will kill the plant.
Pruning: Cut plants down to 6-12 inches in early spring or after frost. This will promote a bushier plant.
