Heart shaped seeds plant weed

Tall morning-glory is a warm-season trailing or climbing annual vine, capable of reaching 6-1/2 feet in length. The stems twine in a dextral (having the whorls coiling clockwise) fashion.

Leaves: Leaves are often heart shaped, sometimes three lobed (both leaf types can occur on the same plant); from 3/8 to 4-5/16 inches long and 3/8 to 4-3/4 inches wide; alternate along the stem; minute flattened hairs usually cover the leaf surface, but sometimes leaves are nearly hairless; petioles range from 3/8 to 5-1/2 inches long.

Flowers: Flowers June to November; flowers grow singly or in clusters of two to five showy, funnel-shaped, stalked, purple, blue, pink, white, or bi-colored; 1 to 3 inches long by 1 to 2 inches wide; sepals at the base of the flower approximately 3/8 to 5/8 inch long.

Fruit: The fruit is a subglobose to ovoid dark brown to black capsule that is approximately 3/8 inch in diameter and up to 1 inch long; contains 3 to 6 wedge-shaped seeds, 3/16 to 5/16 inch long, dull with a granular surface.


Cultivated and disturbed or degraded sites in moist meadows and riparian communities, and roadsides within elevations that generally range from below 7,500 feet.


Reproduces by seed; one plant can produce up to 26,000 seeds; germinating at depths of 4 inches or more, much deeper than most annuals.


Native to Central America; once established, tall morning-glory is difficult to control. Arizona prohibited noxious weed.
