Greatly admired for its true sky-blue flowers borne in profusion in late Summer & Fall, Salvia azurea is also cold hardy, drought tolerant, easy & fast growing. Forming many upright, branching stems from the base, the flowers are held in densely packed whorls at stem ends above dark green, linear foliage. As it matures, it often takes on a lax habit, leaning against its neighbors, so plant it against a fence or between shrubs or roses (like the beautiful yellow ‘Graham Thomas.’). Alternately, you can pinch it back twice during the growing season to create a more dense habit. A good butterfly attractant, too. Average to rich soil is best. Hardy to -20 degrees F. To 5' high & 4' wide.
