Perovskia atriplicifolia Blue Steel (Russian Sage)
Perovskia atriplicifolia 'Blue Steel' (Russian Sage) is an erect, multi-stemmed sub-shrub or deciduous perennial with clouds of small violet-blue flowers on strong silver stems. Blooming for weeks from mid-summer to fall, the colorful blossoms attract pollinating bees and hummingbirds. They are borne on long, silvery stems clad with aromatic, gray-green leaves. Adding long-lasting color to the landscape, this delicate-looking plant is a toughy that is resistant to drought, heat and poor soils. Because of its aromatic foliage and woody stems, few pests, including deer, ever bother it. A perfect perennial for hot, dry climates that is also exceptionally cold hardy. Pretty and excellent for xeriscaping, its long blooming season makes it an extremely valuable addition to the garden – even in winter when the stems create a beautiful feature in the landscape.
- Typically grows up to 18-36 in. tall (45-90 cm) and 14-28 in. wide (35-70 cm).
- Performs best in full sun, in average, dry to medium, well-drained soils.
- Virtually pest and disease free. Drought and salt tolerant, deer and rabbit resistant.
- Attracts scores of butterflies and hummingbirds
- Russian Sage looks stunning in dry landscapes with other desert plants, in cottage or Mediterranean gardens, whether planted as singles or in clusters to intensify its presence, or even in a linear mass for knot gardens or small divider hedges. It associates wonderfully with other gray-leaved plants such as Lavender and contrasts beautifully with the bright colors of Echinacea (Coneflower), Helenium (Sneezeweed) and clump-forming grasses.
- Cut back plants almost to the ground in late winter to early spring as soon as new growth appears.
- Propagate by softwood cuttings in late spring or semi-ripe cuttings in summer
- Perovskia atriplicifolia is native to Central Asia (Afghanistan, Pakistan, etc.) and Tibet at elevations to 8,000 ft.
