A grapefruit (Citrus paradisi) is a sweet orange and pomelo hybrid. The Ruby Red is one of the sweetest grapefruits without losing the unique lovely grapefruit tang. The tree is surprisingly easy to grow. It is drought tolerant and naturally pest and disease resistant.
 
Taste: The deep red juicy flesh offers a perfect blend of sweetness and refreshing tangy flavor.
