About plant names...

Bindweeds, sometimes called wild morning glories, are vines that twine around other plants or trail along the ground. They are native to temperate regions of Europe, Asia, Africa, North America, Australia, and Argentina. Though attractive, they are often considered invasive.

Identification: Plants are vines 20-79" (50-200 cm) high. Leaves are ¾-1¾" (2-5 cm) × ⅜-1" (1-3 cm) wide, either linear or shaped like arrowheads (sagittate). The flowers are trumpet-shaped, ⅜-⅞" (1-2.5 cm) in diameter, and white or pale pink. Seeds are ⅛" (3.2 mm) long, with two flat sides and a convex side, like an orange segment.
