Not here, no. I would surmise that no one on this board has grown longan. I am half-Puerto Rican, however, and on that island we grow what is called quenepa. It appears that quenepa and longan look very, very similar and the berries or fruits you take from them appear almost identical. Does the longan berry stain white clothing brown? If it does, then I'm going to guess that Puerto Rican quenepa is probably really Asian longan.
