Pink's vintage blooms are fragrant with the spicy scent of cloves and bring us back to a time when fragrance, above all else, was treasured. Best crowding border edges and well-drained rock gardens, where it attracts butterflies and bees. If mulching to suppress weeds, use a layer of fine gravel. Deadhead regularly or shear after bloom in summer. Prune any winter-killed stems as growth resumes in spring and divide every two-three years to renew vigor—in early spring for zones 3-6 or fall in zones 7-9.
