Pinkish white flowers in dense spikes just above the silvery green foliage are loaded with nectar, attracting a large number of pollinator insects. Plant in full to partial sunny locations in moisture retentive soils and allow room for the plant to moderately spread by rhizomes over the years. Late summer these plants are swarmed by an incredible number of pollinator insects visiting the nectar loaded flowers. The bruised leaves give off a strong mint fragrance.
