Synonyms (former Scientific Names):
Calystegia sepium ssp. Sepium
Convolvulus sepium var. communis
A vine plant spreading by rhizomes and seed. This plant has a shallow but extensive root system with a stem that usually trails along the ground or climbs foliage and other structures.
Leaves are entire, alternate, and shaped like arrowheads or triangles usually 4 to 15 cm long, with long petioles. Leaves have 5 main points- 4 close to the base and 1 at the tip. The leaves are squared off at the base of the leaf.
This plant can be distinguished by its funnel shaped flowers, climbing stems, and alternate leaf arrangement and leaf shape. It can grow up to 3 meters long, and it is often confused with field bindweed. Field bindweed has a smaller flower and has 2 additional bracts below the 2 leafy bracts on the flower. Field bindweed leaves only have 3 points, are more arrow shaped, and do not square off.

Fruit are 8-10 mm globe shaped capsules containing 2-4 seeds.
Found throughout Canada and the eastern United States. This plant is a problem in rowcrops, orchards, vineyards, and fence rows. Hedge bindweed also serves as an alternate host to tobacco streak virus and cucumber mosaic.
