- This weedy species can be found escaped in a handful of Missouri counties but it will almost certainly expand its range with time. The plant is listed as a noxious weeds in many parts of North America. The fruits of this shrubby tree are quite edible and many animals help spread the seeds into the wild. The roots have nitrogen fixing nodules that enable the plant to survive in weak soils.
There are a few different species of
in Missouri. All are introduced and invasive.
