Other info. - Kudzu is one of the most famous weed pests in the south. The vines can cover entire wooded areas killing or stunting all the vegetation below with shade. It is less a problem in Missouri, at least at present. The species was originally brought to the U.S. as ground cover and fodder and now much research time is being devoted to its eradication.

Missouri plants are assignable to var. lobata.
