Morningglory, pitted (Ipomoea lacunosa)

Summer annual broadleaf

Pitted morningglory

A trailing or climbing annual vine with heart-shaped leaves that taper to a point and attractive funnel-shaped white flowers. Seedlings have cotyledons that are deeply indented and taper to a point (compare with tall, ivyleaf and entireleaf morningglory). Cotyledons are also without hairs (glabrous). Mature plants have leaves that occur on relatively long petioles and are arranged alternately along the stem. Leaves can be without hairs or only slightly hairy, but do not have the appressed hairs typical of tall morningglory. Leaves are heart shaped in outline but taper to a narrow tip, unlike those of tall morningglory.
