Saltmarsh morning glory is a trailing perennial vine found in Florida’s salt, floodplain and glade marshes, mangrove swamps and growing where the natural vegetational cover has been disturbed by humans. Its showy blooms appear in summer and fall. The large nectaries and flowers attract many insects, but it is most visited by bees.
Saltmarsh morning glory flowers are solitary and funnel-shaped with five fused pink -to-purplish petals and a darker throat. Five greenish sepals cup the flower at its base. Sepals and stems are glabrous. Leaves are sagittate with long petioles. They are alternately arranged. Seeds are borne in globose capsules. Tendrils and underground rhizomes give the vine its vigorous mobility.
