I have a large female Garcinia benthamii which is also 5+ meters tall that will occasionally set the odd miniature seedless fruit that ripens to a light orange colour. The tiny amount of flesh in these fruit has a very pleasant taste, so it would be nice to get some full sized fruit. I too find it hard to cut out such a lovely big tree, next season I will try to use pollen from my G.xanthochymus in an attempt to get fruit set.
