History
Florida Ruby Red Grapefruit, initially called "Redblush," was a "limb sport," or spontaneous mutation of a Thompson Grapefruit, itself a sport of the Florida White Marsh Grapefruit. Redblush was first observed by J. B. Webb of Donna, Texas in 1931. Budwood from the limb was grafted onto rough lemon root stock and in 1934 this generally seedless red grapefruit was widely introduced.

The warm, moist climate in Florida fostered a particularly juicy and sweet fruit which was renamed Ruby Red Grapefruit and now comprises the bulk of the state's grapefruit crop.
