Garcinia warrenii

Also known as Native Mangosteen or Twin Mangosteen

Garcinia warrenii is a rare Australian native fruit tree producing small, round reddish-purple fruit with tart-sweet pulp.

The tree is evergreen, with glossy dark green leaves and bright yellow or orange new growth. It’s slow-growing but highly ornamental and suitable for protected spots in warm gardens or larger pots.
