It is a serious aquatic weed problem in the North Carolina coastal plain and is becoming a major pest in pastures and row crops in low-lying areas. Alligatorweed stems are distinctly jointed and hollow except at the nodes. The stems are light green in color, with faint darker green parallel lines extending from one node to the base of the next. Roots are produced at the nodes. Terrestrial infestations produce two types of rhizomes: purplish, horizontal rhizomes that resemble stems with very short internodes, and fleshy, white, rootlike rhizomes. Terrestrial stems usually are pithy or even solid, rather than hollow. Leaves are oval to lance-shaped, have a prominent midrib, and are arranged opposite along the stem. Small, cloverlike, white flowers are borne on short stalks attached in the leaf axils near the end of the stems. Flowering occurs from late April through October. Reproduction is vegetative by fragmentation because very few seeds form.
