Russian Sage, actually a native of Pakistan,is one of the great garden plants of all time. This semiwoody perennial carries a cloud of small blue flowers on widely arching stems that grow 3-4ft tall and as wide. The effect is a charming, airy haze of soft blue against silvery gray, pungently aromatic foliage.Bloom begins in July and continues right through September, which makes Perovskia an exceptionally long-blooming perennial. Plants are vigorous and very hardy, ignoring heat, drought, and pests, while always looking fresh. Hardy in zones 4-8. Prefers full sun. Space the plants 24-30" apart.
