- Description
-
Hedge bindweed is a perennial, herbaceous weedy vine or wildflower in the morning glory family (Convolvulaceae). This vine climbs vertically and spreads horizontally, twinning around objects or other plants and tolerates nearly any growing conditions. It is known to produce allelopathic chemicals that inhibit the growth of other plants near by It can be found growing in disturbed areas including, cropland, pastures, abandoned fields, streams and areas along roadsides and railroads.
The plant is native to Eurasia but is found throughout the continental United States. Many of those states list the plant as a noxious weed. It can be mistaken for large bindweed but the flowers for hedge bindweed have bracts that do not overlap, unlike large bindweed. The plant is difficult to eradicate as is able to regrow from any part of rhizomes left in the ground and also self-seeds.
Diseases, Insects, and Other Plant Problems: No significant problems. This vine can spread aggressively and become a nuisance in some locations.
