The other one to look out for is the Russell's Sweet that Mike has posted about. There is a grafted young tree on the south side of town I know of, but its a loner and possibly wont fruit without a pollinator, unless one of the the other 10 or so Garcinia spp in the same garden will pollinate it. The bumpy madruno is supposed to be among the best, and the smallish brasiliensis is well worth growing in a part shade spot as it fruits early and lots to make up for the small size of fruit. I have a large one in a pot which is root bound, but still produces quite well through the warmer months, but the sun knocks back fruit production during really hot patches (like now). Most of the ex-Rheedias are pretty tough if given a bit of shade. The SE Asian Garcinias are generally a lot more fussy and need the right water and humidity year round and truly hate the intensity of the sun here when 0 cloud cover can kill a 6ft parvifolia or mangostana in half a day.
