More Details

The Rio Red Grapefruit Tree, scientifically known as Citrus paradisi 'Rio Red', is a standout citrus variety celebrated for its large, juicy fruit with a deep red flesh that is both sweet and slightly tart. This variety is a mutation of the Ruby Red Grapefruit and has become highly prized for its excellent fruit quality and attractive, deep red coloration, which is richer and more intense than that of its predecessors. The Rio Red Grapefruit is not only valued for its delicious fruit but also for its ornamental qualities, with glossy green foliage and fragrant white flowers that add beauty to any garden or landscape. Ideal for warm climate gardeners seeking to enjoy fresh grapefruits from their own trees, the Rio Red is tolerant of a variety of soil types, provided they are well-drained.
