Re: Mangosteens and other tropical fruits found in Knoxville!
Here in South Florida, we are lucky enough to have a ton of different fruits that are usually not found north of Orlando. There are even varieties of Apples, Peaches, and Olives that will grow and fruit here! You can actually try most tropical fruits for free at the Fruit & Spice Park in Homestead.
Most tropicals I've tasted have come from friends or the Fruit & Spice Park. I've tasted: Sugar Apple, Custard Apple, Atemoya, Jaboticaba(awesome!), Grumichama, Lychees, Longans, Loquats, Muscadine Grapes, Starfruit, Sapodilla(my favorite), Mamey, Cashew Apple, Guava, Canistel(eggfruit), several types of Bananas, Black & White Sapote, and many many more I can't remember.
Unfortunately, I've never had the pleasure of tasting a mangosteen.
