- Invades forests, open woods, forest edges, pastures, prairies, and roadsides. Dominates hardwood forests shrub layer.
- It is reported as invasive throughout the northeast and midwest.
- Tolerates both full sun and full shade.
- Adaptable to a variety of soil conditions, with high salt tolerance.
- Prolific seed producer with high viability.
- Not palatable to white-tailed deer, resulting in more significant browse damage to native herbaceous plants and other desirable species.
Leaves & stems: Shrubs have wings or distinct corky ridges on the bark and contains. On younger growth, this may be reduced. Leaves are arranged with opposite branches. Leaves are simple, elliptic with finely serrated edges. Foliage turns vibrant red colors in fall.

- Hand-pull seedlings. Use a spading fork or weed wrench to remove larger plants and their root systems.
- Larger plants can be cut, but the stump must be ground out or regrowth frequently monitored and clipped.
- This species can re-sprout after cutting and top-kill herbicides.
- Cut stumps can be painted with herbicide.
- If populations are too large for cutting to be practical, a foliar glyphosate spray can be applied in the early summer months.
- Note that this species can re-sprout after cutting and top-kill herbicides.
