According to wikipedia:
Coccoloba uvifera is a species of flowering plant in the buckwheat family, Polygonaceae, that is native to coastal beaches throughout tropical America and the Caribbean; including southern Florida, the Bahamas, the Greater and Lesser Antilles and Bermuda. Common names include Seagrape and Baygrape.
In late summer it bears green fruit, about 2 cm (0.79 in) diameter, in large grape-like clusters. The fruit gradually ripen to a purplish color. Each contains a large pit that constitutes most of the volume of the fruit.
So I'm a complete and utter flower child loving all things Mother Nature & when I noticed how healthy this year's seagrape crop is in Miami, I'm totally jumping for joy every time I pass their bountiful bundles! I always enjoy native fruits, vegetables & herbs so I'm really overjoyed in anticipation of that plum purple color they will turn when they ripen in the fall. Seagrapes are a sweet, grainy experience similar to pear but with an added tangy twist. :P Can't wait!
