Virginia Tech Weed Identification Guide

Entireleaf Morningglory: Ipomoea hederacea var. integriuscula

Weed Description:  A summer annual, twining or climbing vine with heart-shaped leaves found throughout the Southeast and into the north central and northeastern United States.

Roots:  Taproot.

Stems:  Most often found climbing, hairy, reaching 10 feet in length..

Leaves:  Alternate, heart-shaped, with hairs that stick straight out from the leaf.
  Seedling:  the cotyledons (hypocotyls) are green or purple tinged, without hairs.  Cotyledons have rounded points, are moderately indented and have hairs that stick straight out from the cotyledons.

Flowers:  Petals are purple to pale blue or white and fused into a funnel.

Fruit:  Brown capsules that separate into 3-4 parts when mature.

Identifying Characteristics:  Entireleaf morningglory very closely resembles Tall Morningglory (Ipomoea purpurea), however the two species differ in the orientation of hairs on the cotyledon and/or leaf surfaces.  Tall morningglory leaves have hairs that lie flat (appressed) on the surface, while the hairs on entireleaf morningglory stick straight out from the leaf.
