Latin name - Gardenia gardneriana

Bacupari is a rare member of the mangosteen (Garcinia) family, native to S. America.  Its latin binomial is Gardenia gardneriana. This fruit is distinct from the lemon drop mangosteen and achachairu — though similar in appearance, the Bacupari stands out in both the appearance and leaves of the tree, and the fruit.   The fruit has has a skin/shell that completely separates from the flesh, which is opaque white and doesn't emit juice like a lemon drop mangosteen.  Comparing the fruit, the Bacupari is more similar to the achachairu but still distinct.  While we have not personally seen or picked from from a verified mature Bacupari tree, the appearance of the leaves and stems of the young trees we have indicate that this species may grow a bit more compact overall compared to the achachairu.  A rough estimate of the time to fruiting would be 4-6 years from a 3 gallon size, but don't hold us to it — it could be earlier or later, and depends largely on growing conditions along with age of the tree.  

** Be aware, most of the information/pictures you'll find on the internet when you search for 'Garcinia gardneriana' can be misleading.   The name 'Bacupari' is often misused and most of the listings we saw showed a lemon drop mangosteen, or an achachairu.  This is different from both of those.  Here is a YouTube video which shows the ultimate difference between the fruit of Bacupari (G. gardneriana) and lemon drop mangosteen (G. intermedia or G. brasiliensis, depending on who you ask...)

This tree, like other Garcinia species, is relatively hardy and can endure full sun, partial shade, and moderate drought, although they grow best when temperatures are warm and humidity is high.  We would expect the cold tolerance of Bacupari to be at least 32 degrees Fahrenheit, but potentially as low as the mid-20s.
