Gardeners' Notes:

When I bought my home in St. Petersburg, Florida, zone 9b, in 1988, there was a mature specimen of a Ruby Red grapefruit in my small back yard. I lived there for over nine years, and every winter, no matter what the weather the previous year, this tree was just covered in large, tasty, pink-red fleshed, very juicy grapefruit. They were rather sweeter tasting than regular grapefruit, and I had no problem at all giving away any extras, as one can eat only so many grapefruit at any one time. If you like grapefruit and have the climate to grow them, this is an excellent choice.
