Steeplebush are showy shrubs with long-lived blooms that are perfect for naturalized wetland areas. They spread by basal shoots, or root suckers, to form large colonies and can become invasive if the shoots are not removed. Spent flower steeples should be removed encourage new steeples to bloom. These shrubs flower on new wood, so pruning should be done in late winter, before the plant exits hibernation.
There are few diseases or pest issues that threaten the life of Steeplebush. Leafspot, fireblight, and powdery mildew may appear. Insect pests may include caterpillars, scale, and aphids.
