Culture and Uses:
One of the best shrubs for summer bloom. Grow plants in moist, well-drained soils—they are intolerant of dry conditions. Without leaves plants are not as twiggy as most shrubs, but still have a dense habit because of large compound leaves. Plants are exceptional in masses, in part to full shade, although they will produce fewer flowers in more shade. Their suckering habit allow them to make great borders, but plants do not aggressively spread. Propagate by seed planted in fall, though little seed is produced on plants in northern climates because of short growing season. Dig and separate runners or softwood cuttings in May can also be used for propagation. Fall color is best when plants are happy—sited properly with part-sun and well-drained, moist soils.
