Calystegia sepium

Calystegia sepium, commonly known as the hedge bindweed, morning glory, or bellbind, is a species of flowering plant in the family Convolvulaceae. It is native to both North America and Eurasia, and it has been introduced to other regions globally.

Description

Calystegia sepium is a perennial vine that can grow up to 2-4 meters in height. The plant has large, white or pink flowers that are trumpet-shaped and can reach up to 7 cm in diameter. The leaves are arrowhead-shaped and can be up to 10 cm long. The plant's stems are twining and can climb over other plants and structures.

Habitat and Distribution

Calystegia sepium is found in a variety of habitats, including hedgerows, riverbanks, and woodland edges. It prefers moist, well-drained soils and can tolerate a range of light conditions, from full sun to partial shade. In North America, it is found from southern Canada to northern Mexico, and in Eurasia, it is found from Western Europe to East Asia.

Ecology

Calystegia sepium is a food source for several species of Lepidoptera, including the silver Y moth and the angle shades moth. The plant is also used as a shelter by various small mammals and birds.

Cultivation and Uses

While Calystegia sepium is often considered a weed due to its aggressive growth habit, it is also cultivated for its attractive flowers. It can be used in gardens as a climbing plant to cover walls and fences. However, care should be taken to prevent it from overgrowing and smothering other plants.

Control

Control of Calystegia sepium can be challenging due to its deep, extensive root system. Methods of control include hand-pulling, mowing, and the use of herbicides. However, these methods can be labor-intensive and may not be fully effective.
