Mangosteen is a small and very slow-growing tropical evergreen tree. The height of the tree attains 20 to 82 feet. The length of its leaves is up to 10 inches. The width of its flowers is 1 ½ to 2 inches. And maybe male or hermaphrodite is on the same tree.
Mangosteen is native to South East Asia and requires a year round, warm, very humid, equatorial climate. In spite of that, many people have tried to plant Mangosteen in other places, such as California, Florida, or special greenhouses somewhere outside South East Asia. The outcome is seldom successful due to the different living conditions. The tree only can grow well in tropical areas and requires abundant moisture. Thailand or Burma are the original countries people found Mangosteen in. Recently tropical Australia has been found to be an excellent area for Mangosteen production.
I have found them in the Philippines and in Vietnam. It was my Mother's favorite fruit.
Much has been made of the extensive antioxidant properties of vitamins, especially Vitamin C and Vitamin E that is found in the mangosteen fruit.
