Larger Bindweed - Calystegia sepium
Calystegia sepium (Larger Bindweed, Hedge Bindweed, Hedge False Bindweed, or Rutland beauty) (formerly Convolvulus sepium) is a species of bindweed, with a subcosmopolitan distribution throughout temperate Northern Hemisphere in Europe, Asia, northwestern Africa, and North America, and in the temperate Southern Hemisphere in Australia, and Argentina in South America. Perennial from rhizomes, trailing or climbing vine to 10 feet long, with distinct triangular leaves. Found throughout the eastern United States to the Great Plains, and also in the upper northwestern states.
It is a 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 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.
Calystegia sepium is an attractive plant with showy flowers. However, because of its quick growth and clinging vines, 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. The suggested method of eradicating Calystegia sepium is vigilant hand weeding.
This weed is often mistaken for Field Bindweed (Convolvulus arvensis). 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 hedge bindweed.
