Grapefruit.

The grapefruit (Citrus × paradisi) is a subtropical citrus tree known for its sour to semi-sweet fruit.

Grapefruit is a hybrid originating in Barbados as an accidental cross between two introduced species, sweet orange (C. sinesis) and pomelo or shaddock (C. maxima), both of which were introduced from Asia in the seventeenth century.

When found, it was named the “forbidden fruit”; and it has also been misidentified with the pomelo.

GreenPoint’s Grapefruit take 480 acres out of cultivation and are commercialized from November to April.
