Why is it listed as a Noxious Weed?
This popular ornamental shrub has been establishing in not only disturbed areas, but natural areas as well, where it has negative ecological impacts and is difficult to control.
It forms dense thickets, especially along river banks and river gravel bars, which crowd out native vegetation and may alter soil nutrient concentrations.
The seeds, so easily spread by wind or water, can remain in the seed bank for three to five years.
This shrub can begin producing seeds during its first year.
Once established, this shrub is difficult to remove. It will resprout from the rootstock after its stems are cut, and the cut stems can also grow into new plants.
