The Perennial Sages are invaluable perennials for their rich display in the border. Plants form a bushy clump of grey-green leaves, with upright spikes appearing in early summer, attractive to both butterflies and hummingbirds. This taller selection has flowers 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. Excellent for cutting. Clumps may be easily divided in early spring, every 3 to 4 years.
