Identifying Characteristics

Size/Form: Seagrapes have unusually thick trunks that branch out close to the ground.
Bark: The thick, smooth bark has patches of white, gray, and light brown. When cut, the bark exudes an astringent red sap.
Twigs: Twigs are thick, smooth, and stout. Color is orange to brown.
Leaves: The leaves are shiny, leathery, and nearly circular. The leaf arrangement is alternate. The leaves are about 8" in diameter with a large, reddish center vein. The leaves may be a shade of orange when young, green when mature and rust color when older, right before they drop. One distinctive family characteristic is the collar-like sheath called an "ochrea" that is formed around the stem just above each attachment to a petiole.
Flowers: The flowers, which are small and greenish-white, begin to appear in clusters when the plant is 6 to 8 years old. Male and female flowers appear on separate trees.
Fruit: The fruits are spherical and slightly smaller than a table grape. They hang in bunches and mature from green to a vibrant purple.
Similar Trees on the Florida 4-H Forest Ecology Contest List:
  • None. The leaf shape and leaf coloring, along with the presence of an ochrea, should make this species easy to recognize.
