The fruit has to be almost rotted before you eat it, it's ... shall we say ... an aquired taste *G* I tried to grow this a couple of time from seed, I suppose I shall just have to save up and buy the tree.
Baa, we found a seedpod (or fruit?) that was withered, and it was impossible to break open with our fingers. We both tried. Didn't feel we should rip one off the tree and steal it to try to get seeds from it though. Bad policy in a public park (and even more so in a private garden). But maybe when I go there to volunteer in a few more weeks I can ask for a seedpod. Worth a try!
