Due to its high salt tolerance the Seagrape is used extensively in seaside planting to help stabilize dunes. The large round, leathery leaves with red veins form a dense spreading canopy. The shape of the mature tree depends in large part on the location at which it grows. A more exposed wind swept location along the beach will lead to smaller more gnarled trees while further inland the canopy will grow into more of a broad vase shape. The Seagrape prefers full sunlight and sandy well-drained soils and is drought resistant but cold intolerant.
The female trees produce grapes that start out green and turn dark purple as they ripen. The grapes are edible and can be used to make jelly. They are also a favorite food source for many different kinds of wildlife.
The leaves and fruit can be a nuisance if planted in the wrong place. The fruits will drop to the ground and leave stains on roads or pavement while the leafs are very slow to decay.
