Practical Weed Science for the Field Scout: Corn and Soybeans

Morningglory, palmleaf (Ipomoea wrightii)

Summer annual broadleaf

A trailing or climbing annual vine with lobed leaves and pink to light purple flowers that range from 3/4 to 1 inch in length. Palmleaf morningglory is primarily a weed of agronomic crops found in the southeastern United States. Seedlings have cotyledons that are deeply indented, have pointed ends and are without hairs. The cotyledons of palmleaf morningglory closely resemble those of pitted morningglory. Mature plants have leaves that are distinctly lobed into three to seven segments, giving the overall appearance of fingers on a hand. Individual segments range from 3/4 to 2-1/2 inches long. All lobes arise from the same point.
