A citrus fruit with an orange, porous exterior, and a bright peachy-pink interior. They are juicy and tart in flavor.
Grapefruits originated in Barbados as a hybrid fruit, a cross of the pomelo (or pummelo) with the orange (both introduced from Asia).
In 1823, William C. Cooper, a U.S. Department of Agriculture citrus scientist, introduced grapefruit seeds to the area of Tampa, Florida, from the Bahamas.
The name “grapefruit” comes from the way the fruit grows on the trees; in clusters resembling large grape bunches.
