Practical Weed Science for the Field Scout: Corn and Soybean

Morningglory, tall (Ipomoea purpurea)

Summer annual broadleaf

Tall morninggloryTall morningglory
 

Tall morninggloryA trailing or climbing annual vine with heart-shaped leaves and purple to white flowers. Seedlings have cotyledons that are only moderately indented as compared with either pitted or palmleaf morningglory. Cotyledon lobes are rounded and not pointed to any degree and cotyledons are also almost perfectly square in outline. The first true leaf is heart shaped as are all subsequent leaves, but the first true leaf often is without hairs unlike the subsequent leaves. Mature leaves are arranged alternately along the stem and have hairs that lie flat against the leaf surface, unlike entireleaf morningglory. Older leaves have rounded bases that often overlap.
