Summary

Ipomoea sagittata, commonly known as Saltmarsh Morning-Glory, is a perennial vine native to coastal wetlands, salt marshes, and dune systems in the Southeastern United States, the Caribbean, and Mexico. It is particularly adapted to brackish environments. This species typically sprawls or climbs to heights of 0.5-9 feet and can spread 0.5-1 feet wide. The Saltmarsh Morning-Glory is characterized by its arrow-shaped leaves and showy, trumpet-shaped flowers that are usually pink or purplish in color, blooming from summer to early fall. The flowers are especially attractive to pollinators such as bees and butterflies.

In cultivation, the Saltmarsh Morning-Glory is valued for its ability to thrive in challenging coastal conditions, including saline soils and periodic flooding. It is often used for naturalizing in wetland restoration projects, as well as for ornamental purposes in water gardens or as a ground cover in coastal landscapes. This plant prefers full sun exposure and can tolerate a range of soil drainage conditions, from slow to fast. While it requires medium amounts of water, it is relatively low maintenance once established. Gardeners should be aware that in some areas, it can become aggressive and may require management to prevent it from overtaking other plantings.CC BY-SA 4.0
