The Perennial Sages are invaluable for their rich display of spiky flowers in the early summer border. This selection is medium in size, with flowers of deep indigo violet-blue. Remove faded blooms to encourage repeat flowering. Excellent for cutting. Drought tolerant, once established. Also tolerates heat and humidity. Plants may be easily divided in early spring or fall. Can be clipped back hard after blooming, to rejuvenate the foliage. Attractive to both butterflies and hummingbirds. A former Perennial Plant of the Year for 1997.
USDA Zones: 3-9
