The Rio Red grapefruit is a fairly novel variety discovered in 1976 by Richard Hensz at Texas A&M. It was introduced to the public in 1984. It is slowly gaining popularity due to its sweet flavor and juicy red flesh.

Be cautious if you are new to grapefruits, and always talk to your doctor before consuming grapefruit flesh. They contain certain compounds that can cause drug interactions.

How tall does a Rio Red grapefruit tree grow?

The growth may be limited in a pot, but even tiny trees can produce over 25 pounds of fruit each year.
