Set out plants in spring or fall, spacing 8 to 12 inches apart. Choose a location in sun or light shade, bearing in mind that farther south, plants will be happier with more shade. Any good, welldrained soil is fine.
Keep soil moist, particularly when plants are situated in full sun; a moisture-conserving summer mulch is helpful to this end. To maintain plants’ health and beauty, cut back old foliage in the spring before new growth emerges.
