A native of tropical America, now widespread in the United States due to its use as an ornamental planting.
An attractive annual vine that reproduces only by seeds that germinate in early summer. It is a very rapid grower and climber, and becomes a problem in many cultivated crops, orchards, or vineyards.
Similar to Tall Morningglory, but with leaves that vary in shape, but typically have 3 to 5 distinct lobes. It has a taproot, while Tall morningglory has a fibrous root sytem.
Leaves are very large, up to 3.5 inches long. Flowers occur on short stalks that arise from the leaf axils, with from 1 to 3 large bluish to purple flowers. Petals are fused to form a funnel about 1.5 to 2.5 inches across.
Characteristicts Important to Control:
An annual vine growing only from seeds. Rapid growth causes problems, but physical removal of individual plants will work.
