Description

Calystegia sepium, or Hedge Bindweed, is a perennial, herbaceous weedy vine or wildflower in the morning glory family. 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 and spreads quickly by rhizomatous roots and seeds. It can be found growing in disturbed areas including, cropland, pastures, abandoned fields, stream 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 Field Bindweed; however, field bindweed leaves are smaller, with a more rounded apex, and bases that are pointed or rounded, but not cut off squarely across the top as in Calystegia sepium. The root system of Hedge Bindweed is fibrous and rhizomatous, and it may extend into the ground up to 10 feet, making it difficult to remove once established. It is capable of re-growing from any part of the root left in the ground. Hedge Bindweed spreads by clonal offshoots from its rhizomes or by reseeding itself. 

Diseases, Insects, and Other Plant Problems:

No known diseases or insect problems. This vine can spread aggressively and become a nuisance in some locations.

These seeds are dull brown to black, 3-angled (two flat sides and one rounded side), and rather irregular in shape; they are a little less than ¼ inch long.

    Flower Description:

The large buds produce flowers with corollas that are usually white, although sometimes they are pale pink with spreading white stripes. However, deep within their throats the corollas are yellow. The flowers open during the morning and usually close at around noon, although they may remain open longer on cloudy days. The blooming period occurs intermittently during the summer for about 1-3 months. However, individual flowers last only a single day.
