Summer annual broadleaf

Ivyleaf morningglory

A summer annual twining or climbing vine with distinctive three-lobed leaves and large, showy, funnel-shaped purple to blue or white flowers. Seedlings have cotyledons that are only shallowly or moderately indented, and with a slight flare outward. The cotyledons of ivyleaf morningglory most closely resemble those of entireleaf and tall morningglory. However, the cotyledons of tall morningglory are usually more square in outline than those of ivyleaf or entireleaf morningglory. The first true leaf is unlobed. Subsequent leaves are alternate, three-lobed or ivy-shaped, with hairs that stick straight out from the leaf.
