Overview

Comprehensive Description

Description

A native perennial vine that is up to 10' long, often climbing over other herbaceous plants and shrubs. The twining stems are light green or red, upon which the leaves occur rather sparsely. These leaves are about 4-5" and 2-3" across when mature. They often have an arrowhead shape, which is deeply incised at the base. Otherwise, they are cordate, deltoid, or ovate, with different forms occurring even on the same plant. The flowering buds are white or light lavender, from which funnel-shaped flowers unfurl that assume the same colors. Each flower is about 2½-3" across and has a yellow throat, from which the sexual organs barely protrude, appearing as a small white spike. The flowers open during the morning, and bloom sporadically all summer during sunny weather. The root system is fibrous and rhizomatous, and may extend into the ground up to 10'. American Bindweed spreads vegetatively and by seeds.

Comments

Some greenhouse studies (Quinn, 1974) indicate that Hedge Bindweed has allelopathic tendencies, which no doubt contributes to its aggressive nature. The flowers are showy and attractive when fully open. This plant also occurs in the Old World; different varieties have been identified.

Range and Habitat in Illinois

Hedge Bindweed occurs throughout Illinois, especially in the central and northern areas (see Distribution Map). It is considered a noxious weed in a few states, but is not listed as such in Illinois. In natural areas, this plant occurs at the edges of moist to mesic prairies, thickets, woodland borders, and floodplain areas along lakes and rivers.. Habitats in developed areas include cropland, pastures, abandoned fields, fence rows, urban waste areas, or areas along roadsides and railroads, where it is frequently encountered. Hedge Bindweed is more common in disturbed areas.

Associations

Faunal Associations

Long-tongued bees are the primary pollinators of the flowers, including bumblebees, Little Carpenter bees, and the oligoleges Melitoma taurea (Mallow Bee), Peponapis pruinosa pruinosa (Squash & Gourd Bee), and Cemolobus ipomoea (Morning Glory Bee). It is possible that day-flying Sphinx moths may visit the flowers during the morning. All of these insects seek nectar. The foilage is eaten by the caterpillars of Emmelina monodictyla (Common Plume Moth), as well as several Tortoise Beetles, including Chelymorpha cassidea (Argus Tortoise Beetle). Mammalian herbivores tend to ignore this plant when other food sources are available. To a limited extent, the Bobwhite and Ring-Necked Pheasant eat the seeds.

Relevance to Humans and Ecosystems

Benefits

Cultivation

This is an easy and adaptable plant, preferring full to partial sun and moist to mesic conditions. It tolerates poor soil, often flourishing in areas that are rocky or gravelly. American Bindweed readily climbs a trellis, fences, and neighboring plants, while in open areas it sprawls haphazardly across the ground. The climbing ability is the result of the stems twining tightly about slender objects. This plant can spread aggressively and become a nuisance in some locations.

Calystegia sepium

Calystegia sepium (larger bindweed, hedge bindweed, Rutland beauty, bugle vine, heavenly trumpets, bellbind) (formerly Convolvulus sepium) is a species of bindweed, with a subcosmopolitan distribution throughout the temperate Northern and Southern hemispheres.

It is an herbaceous perennial that twines around other plants, in a counter-clockwise direction, to a height of up to 2–4 m, rarely 5 m. The pale matte green leaves are arranged spirally, simple, pointed at the tip and arrowhead shaped, 5–10 cm long and 3–7 cm broad.

The flowers are produced from late spring to the end of summer. In the bud, they are covered by large bracts which remain and continue to cover sepals. The open flowers are trumpet-shaped, 3–7 cm diameter, white, or pale pink with white stripes. After flowering the fruit develops as an almost spherical capsule 1 cm diameter containing two to four large, black seeds that are shaped like quartered oranges. The seeds disperse and thrive in fields, borders, roadsides and open woods.

Several regional subspecies have been described, but they are not considered distinct by all authorities:

Other vernacular names include greater bindweed, bearbind, hedge convolvulus, hooded bindweed, old man's nightcap, wild morning glory, bride's gown, wedlock (referring to the white gown-like flowers and the binding nature of the vine), white witches hat, belle of the ball.

Eradication[edit]

Calystegia sepium flower and foliage.

Calystegia sepium is a plant with showy white flowers. However, because of its quick growth, clinging vines and broad leaves, it can overwhelm and pull down cultivated plants including shrubs and small trees. Its aggressive self-seeding (seeds can remain viable as long as 30 years) and the success of its creeping roots (they can be as long as 3–4 m) cause it to be a persistent weed and have led to its classification as a noxious weed.[who?]

Names and Taxonomy

Taxonomy

Comments: Several native subspecies (as well as exotic subspecies) of Calystegia sepium recognized by Kartesz (1999), following Brummitt's treatment. Some U.S. reports of "ssp. sepium" as native may instead apply to other subspecies; in sense of Kartesz, ssp. sepium is non-native. Sometimes classified in the genus Convolvulus.
