Hedge Or Great Bindweed   Convolvulus sepium

Hedge Or Great Bindweed - Convolvulus sepium

Roadsides, fields and thickets, usually in moist soil, Newfoundland to British Columbia, south to Georgia and New Mexico. Often a troublesome weed. Flowering from June to August. The pink and white flowered form is thought by some to be the native form of this species, which is in part introduced and naturalized from Europe.

The Small Bindweed (Convolvulus arvensis Linnaeus) is smaller in every way, trailing on the ground, the leaves 1 to 2 inches long, sagittate or hastate at the base; flowers pink or nearly white, about 11/2 inches long. Native of Europe and common as a weed in fields and waste places.

The Trailing or Hedge Bindweed (Convolvulusrepens Linnaeus) resembles the Great Bindweed, but is more softly hairy or tomentose. Leaves ovate or oblong, cordate or sagittate at the base. Flowers pink or white, about 2 inches long. It is common in moist thickets and marshes along the coast.
