The Perennial Sages are invaluable for their rich display of spiky flowers in the early summer border. This Dutch strain is compact, with chubby spikes of deep violet-blue flowers. Remove faded blooms to encourage repeat flowering. Excellent for cutting. Drought tolerant once established. Can be clipped back hard after blooming, to rejuvenate the foliage. Attractive to both butterflies and hummingbirds. Ideal for the border edge or in containers. Bred and introduced by Kieft Seeds of the Netherlands.
