How to identify a mangosteen tree

Garcinia mangostana · also called manggis (Indonesian/Malay), mangostán (Spanish)

The 'queen of fruits': a thick purple rind hides sweet-tart white segments. Among the slowest tropical fruit trees to bear and notoriously fussy about climate outside Southeast Asia.

Field marks

These features are typical of the genus Garcinia, so they help confirm you are looking at the right group; the fruit and the details below separate the species.

Leaves are simple and opposite (in pairs), usually thick, leathery and glossy.
Cut twigs, bark or unripe fruit of many species ooze a yellow latex, a strong clue for the genus.
Fruit usually keeps a persistent calyx (the green cap at the stem end); mangosteen's is a round, dark purple berry.

Check a photo

Photograph one whole, mature leaf from above, or a flower or fruit, and the identifier will return ranked matches. If mangosteen is the top result, the field marks above are your second opinion.

Leaves, flowers, fruit, or bark — closer and sharper identifies better. Your photo is identified and discarded, never stored.

Where and when you will find it

Origin / cultivation history: Malay Archipelago (exact wild origin uncertain, possibly of hybrid origin)
USDA zones: 10b-11
Climate: Tropical humid lowland, no strong dry season preferred; deep, well-drained soil; very frost sensitive and notoriously slow to establish outside its native range.
Fruiting season: June, July, August and September (typical, Northern Hemisphere)
How often grown: Uncommon in cultivation

Fruit is the most reliable way to confirm an identification, so June, July, August and September is the easiest window. Outside it, rely on the leaves and the overall habit. A tree growing well outside the climate above is more likely to be a look-alike.

Growing it: seedling or grafted?

A young tree with no fruit is harder to identify and easy to mislabel, so it helps to know how long it takes to reach fruiting age and how it is usually propagated.

Years to first fruit: Seedling 8-15 yrs; no reliable grafted/vegetative method in wide use — most cultivated trees are apomictic seedlings, effectively true-to-type
Propagation: Seed (apomictic — seedlings are genetically uniform, so grafting is rarely needed but rootstock incompatibility research is ongoing).

Relatives in the Clusiaceae family

Close relatives share many features, so these are the most likely mix-ups.
