About plant names...

Bindweeds, sometimes called wild morning glories, are vines that twine around other plants. They are native to temperate regions of Europe, Asia, Africa, North America, Australia, and Argentina. They are attractive, but they are aggressive and, in some areas, invasive.

Identification: This species is a vine that climbs up to about 12' (3.7 m). The vine itself is light green or red. The flowers are trumpet-shaped, up to 3" (7.6 cm) across, usually white, occasionally pink and white, with a yellow throat. (If you have seen morning glories, you will recognize these flowers.) Leaves are shaped like arrowheads (sagittate). Seed pods are nearly round, containing two seeds looking similar to orange segments.
