I've seen a very few planted in landscapes and in arboretums; it never has been or is going to be a popular landscape plant that many seek out. This large shrub is native to the Southeast from northern Florida, areas of Alabama & Georgia & South Carolina, & North Carolina & Virginia and eastern Tennessee & Kentucky. Some native plant and specialty nurseries offer some. It is fast growing. It is brittle wooded and is best sheltered from strong winds. It spreads by ground suckers to become a colony. Its twigs are velvety with thick bristly hairs. Its bluish-green compound leaves have 7 to 13 leaflets, no good fall colour.
