Deciduous, Shrubs, Flowers
Asian natives valued for their contribution of cool blue to flower borders from midsummer to frost. Bear dense stalked clusters of small flowers on current season’s growth. Erect form. Leaves and flowers are aromatic.
Generally grown as woody-based perennials: if plants don’t freeze back in winter, cut them nearly to the ground before spring growth flush to ensure a good base for the new season’s growth.
