Hiya GT, good question. lol
We long ago gave up on lychees and such like, too high, too many predators. But this pulasan, because it was along the boundary, we let grow, and it sure did. It flowers at times but I can't recall a crop. Heck, I'm not even sure it's a pulasan though it does have lighter leaves, yet a stalk of flowers similarly, so not a lychee., I got it when the Rare Fruit Council was active in Mossman long years ago. Was painful to have partner chainsaw while carrying some flowers but figgered it might come back with renewed vigour. So I guess that's no answer to you at all!.
