Arvind , It all depends on where it grows ( type of soil , water , fertilized by cattle ) like I mentioned in a previous message . Shape and height is very different . Some grow like a Christmas tree ( or like a Mangosteen ) others have an almost round canopy , others go straight up . I would say an average of 10 meters .
Just for fun , I planted one inside my orchard in the worst type of soil , almost never water it . If it were an animal I'd be put in jail for animal-cruelty . I kept , read : the most unprofessional pruning anyone could do , slashing away with the machete to keep it around 3 meters . Doesn't give a damn....Flowering again right now , seems early, too bad I never made a note of flowering time for the previous years .
Wow this species can be the most hardiest species of garcinia known to mankind.Also in malaysia where i live the purple mangosteen can be the most choosiest plant demanding a lot in terms of soil and sunlight.This mexican garcinia holds a lot of potential because it can be grown in placest where purple mangosteen cannot grow especially in drier areas.After some googling i got to know that Jalisco is known for its dry deciduos forest.This means your mangosteen can be grown in many places such as in India, northern coast of east java , east of lesser sunda( Flores ,sumbawa,sumba),drier region of africa and many more places
