Breaking the monotone of sage blues and pinks, Silvertone adds luminous quality to the midborder. Clumps grow to 2' and rebloom, extending the season. Spikes stay upright, producing gorgeous displays from late spring to summer. Grow in well-drained, rich soil in full sun. Blends well with other drought-tolerant plants, such as sedums, grasses, asters and other daisies.
