Ipomoea sagittata.
Saltmarsh Morning Glory is perennial flowering vine native to the coastal regions of the southeastern United States where it can often be found growing on barrier islands, at the edges of salt marshes, and in hardwood hammocks.
Salt-tolerant vines can reach over 12 feet in height and are fond of sandy, moist, and even brackish soil, and help to stabilize soil and prevent erosion.
Pink to purple, trumpet-shaped blossoms, which measure up to 3 inches across, open with the morning sun and close late in the afternoon, creating a beautiful display of color throughout the summer months and into early fall.
In warmer climates, such as southern Florida, the flowers will continually bloom as long as temperatures remain above freezing.
Attracts native bees, butterflies, and hummingbirds, and is the host plant for the Morning-glory Plume Moth, Morning-glory Hawk Moth, and the Pink-Spotted Hawk Moth.
