Gardeners' Notes:

The most delicious grapefruit of all. It's hardy only to zone 9a, but it has great ornamental value and can be kept in a large container and brought in for the winter in colder areas. Like other citrus plants, the scent when it's flowering is divine. Grows true from seed.

The best (now probably most popular) home-grown variety of red flesh grapefruit in the gulf-coast. Compact (compared to other grapefruits), delicious and nutritious. 1/2 grapefruit has more cancer/heart disease fighting fiber than a bowl of oatmeal, and almost as much "available" lycopene as a red tomato.
