By the time that some botanists discovered this species for western botany, its native range has been almost all of Alabama & Mississippi, northwest Florida, eastern Georgia, some of Louisiana, and southern Tennessee. It is sold and grows well in the Chicago, IL area in Zone 5a, though a powerful cold winter can do some harm, but this shows it must have had a larger native range in the past. It has a coarse texture, but it is a lovely shrub for gardens and landscapes with good foliage, good fall color, pretty and large flower clusters, a basically neat habit, and bronzy papery bark. I've seen this species about 4 to 8 feet high. It does ground sucker some, but it is easy to prune. It is somewhat commonly planted in the South, the Mid-Atlantic, the Midwest, and the Northeast USA; used more often by landscape designers than the general public; the former who know it better. The are several cultivars that are available with different sizes of the shrub or leaves and variations in flower structure and size. The mother species and most cultivars have both fertile and infertile flowers, so it does produce pollen and nectar for pollinators. Best to prune after flowering in August for best blooming the following year. Its root system is fibrous with shallow lateral roots and it is stoloniferous with lateral shoots, and it is easy to transplant.

Honey bees get nectar and pollen from this plant.
