About

The grapefruit (Citrus × paradisi) is a subtropical citrus tree known for its relatively large, sour to semi-sweet, somewhat bitter fruit. The flesh of the fruit is segmented and varies in color from pale yellow to dark red.

Grapefruits originated in Barbados in the 18th century. They are a citrus hybrid that was created through an accidental cross between the sweet orange (C. × sinensis) and the pomelo (C. maxima), both of which were introduced to the Caribbean from Asia in the 17th century. It has also been called the 'forbidden fruit'. In the past it was called the pomelo, but that term is now mostly used as the common name for Citrus maxima.
