Prefers bright shade and humus-rich, moist, well-drained soil, but will tolerate average to dry soils and full shade.
Blue leaved varieties will maintain the best color in cool, light shade. Many variegated varieties will lose some of their variegation in the heat of summer or when grown in deep shade.
Very drought tolerant once established, they will look their best if provided ample moisture and light fertilization in spring. They can grow in sandy to clay soils. They are attractive to butterflies and hummingbirds and can be grown under black walnut trees.
