We don’t really know anything about this mango, but planted a tree in 2017 for observation.
In 2018, the small tree was allowed to carry a fruit to maturity, which didn't seem to set the growth back. Subsequently, after flushing growth, the tree flowered again in the off-season and had 3 ripe fruits in December.
The fruit is small, yellow, sigmoid shaped with fiberless flesh that has an Indochinese flavor. Its off-season fruit production made us think it could be Chokanon (though the flavor seemed different), or a related Thai cultivar known as 'Sam Ru Du'.
At this point we still aren't sure of its origins and will continue to evaluate it.
