Vine Weeds of Missouri

Field bindweed (Convolvulus arvensis)

Field bindweedField bindweed has been labeled as one of the worst weeds in North America. Shoots emerge f rom rhizomes, but the plant also produces seeds. Rhizomes that are spread by cultivation may initiate plants in areas that were previously not infested with the weed. If emerging from seed, field bindweed's cotyledons are square or kidneyshaped with a small notch in their tip. The plant's leaves are lobed at their base with the lobes pointing away from the petioles. The leaves occur alternately along the stems. The funnel-shaped flowers are usually white, although sometimes they are pink, and have the approximate diameter of a quarter.

A closely related species is hedge bindweed, Calystegia sepium. Hedge bindweed can be distinguished from field bindweed by its larger leaf size and by the square lobes of the leaf base.
