Riverside Morning Glory
(Hedge False Bindweed - Hedge Bindweed - Large Bindweed)
Calystegia sepium
Convolvulaceae (Morning Glory) Family

Plant is a trailing or climbing vine with annual stem. Preferred habitat is roadsides, ditches, disturbed sites and stream banks. Distribution is throughout the Escambia region.

Leaves are triangular in shape; two to five inches long; somewhat arrowhead shaped with lobes curving downward at base; no teeth; forms an angle to the left with sides less than equal, sharp pointed at tip.

Flower is solitary in the leaf axil. Calyx is five lobed; snowy white (occasionally pink); large; 3-5 inches diameter; bell shaped. The two linear stigmas separates this species from Ipomoea, which has globose (globe-like) stigmas. Flowers occur in the spring and summer.

Fruit is a capsule.

The membrane-like petals are sensitive to weight and may collapse at the touch or during heavy rainfall, or perhaps the weight of an insect. The roots of Calystegia are reported to be poisonous. The descriptive Latin “sepium” refers to the rotting leaf litter which stains the skin and clothing and may also be rendered to a crude dye or ink.
