Grapefruit trees have a fascinating citrus history and have long been associated with Florida, where the warm climate helps develop their distinctive balance of sweetness and tartness. Grapefruit varieties range from pale yellow-fleshed types to beautiful pink and deep red selections, with noticeable differences in sweetness, acidity, seediness, and harvest season. The fruit actually gets its name from the unusual way it can grow in clusters on the tree, resembling bunches of grapes.
