A terrible uber-weed. Foliage dies back after frost, however the plant quickly re-establishes itself through persistent underground tubers or 'nuts'.

Growth habit is strongly rhizomatous and one new seedling can quickly establish a large colony by the end of the growing season soley through vegetative reproduction. Also highly resistant to readily availible herbicides like Roundup or Weed-B-Gone. Shading and prevention of tuber set in the fall seems to be the best control.
