Featuring clouds of tiny light blue flowers on spikes and finely dissected, fragrant, gray-green leaves, Russian sage (Perovskia atriplicifolia) works well for perennial borders, mixed borders, wildlife gardens and other landscape areas. This drought-tolerant, woody-based perennial is hardy in U.S. Department of Agriculture plant hardiness zones 5 through 9, and grows 3 to 5 feet tall and 2 to 4 feet wide. Its two-lipped, tubular flowers appear in summer through fall.
Perennial and Mixed Borders
Russian sage works well as a perennial border and in mixed borders that include perennials, bulbs, shrubs, evergreens and other plants When paired with evergreens, the plant's blue flowers create an interesting color contrast. When summer's blue flowers fade, Russian sage continues to stand tall in warm climates and add vertical interest to garden beds. Standing tall is sometimes a problem for Russian sage, however, as it tends to flop over when it gets tall. To prevent this, plant supportive plants around it and make sure the sage gets full sun.
Plant Russian sage toward the back of the border, where it adds height and doesn't screen smaller plants. This low-maintenance perennial tolerates dry, rocky, chalky and alkaline soil, and its salt tolerance means it grows well in coastal gardens. Prune the plants to 6 inches above the soil surface in spring, as new growth provides the best flowering. Before and after pruning Russian sage, sterilize pruning shear blades by wiping them with a cloth dipped in rubbing alcohol.
Russian sage works beautifully in informal wildlife gardens, providing a hazy background of blooms that last all summer long and well into September. This fragrant plant attracts butterflies and hummingbirds while resisting more destructive garden visitors like deer and rabbits. The fine, crowded stems of the plant offer shelter to beneficial insects as well. For a natural look, plant your Russian sage in odd-numbered groups of three, five or seven plants. If you want to add an extra burst of color, consider pairing pink flowers with the sage for an attractive contrast.
Household Uses of Sage
The Russian sage is a distant relative of the mint family but is not the same as the sage commonly used as a spice. There are, however, still many Russian sage uses. Though the leaves of the Russian sage plant are slightly toxic and you should not eat them, the plant's flowers are edible and have a peppery flavor. You can use the leaves for garnish or steep them in a tea that many claim eases digestive discomfort. While you can't east Russian sage leaves, you can dry them to make a fragrant potpourri. You can also dry complete stalks of the Russian sage plant for use in dried flower arrangements.
Russian Sage Varieties
Cultivars of Russian sage have a range of uses in gardens too. Russian sage "Little Spire" (Perovskia atriplicifolia "Little Spire") grows 1 1/2 to 2 feet tall and wide, and provides informal hedging and edging for paths. This compact plant also grows well in containers. Russian sage "Filigran" (Perovskia "Filigran") grows 2 to 4 feet tall and 2 to 3 feet wide, featuring lacy silvery foliage, which looks decorative in an ornamental border. Russian sage "Longin" (Perovskia "Longin") grows 3 to 4 feet tall and 2 to 3 feet wide, and has an upright habit, making it a useful vertical contrast to rounded, bushy plants. "Little Spire," "Filigran" and "Longin" are hardy in USDA zones 5 through 9.
