Perovskia atriplicifolia ‘Blue Steel’, commonly called Russian Sage, displays aromatic, grey-green foliage on a shrubby, deciduous perennial. Silvery-spikes holding clusters of tiny violet-blue flowers crown this plant in the Summer. Grow in well-drained soil. Tolerant of dry conditions but performs best with regular water. Prune back hard in early Spring to promote vigorous growth.
