The Perennial Sages are invaluable perennials for their rich display in the border. They form bushy mounds of grey-green leaves, with spikes of flowers in early summer, attractive to both butterflies and hummingbirds. This particularly compact selection produces spikes of deep violet-blue. Remove faded flowers to encourage repeat blooming, or simply cut back hard after flowering is finished. Plants are reasonably drought tolerant, once established.
