Biology
Hedge bindweed is a trailing or climbing (twining) perennial plant which spreads aggressively by creeping underground stems and by seeds. Large (one to five inches), dark green, heart-shaped leaves with long petioles alternate along the long stems. Conspicuous, large, white to pink flowers occur singly in leaf axils. Flowers may be one to three inches long. Each flower produces two to four seeds in a round fruit. The first leaves of seedling plants have a distinctive notch at the tip. This plant is distinguished from the closely related field bindweed (Convolvulus arvensis) by the two large, leaf-like bracts which enclose the base of the flowers and by the large heart-shaped (not arrowhead-shaped) leaves. SPECIAL INFORMATION: This is an aggressive, spreading plant that is difficult to control. It can resprout from segments of rhizomes left in the soil.
Habitat
Hedge bindweed can become a problem along fencerows, in fields, waste areas, and particularly in ornamental plantings.
