I'm sprouting a ton of flying dragon and I would like to know the true hardiness of the tree itself? I have seen sites say that it is hardy even down to zone 4 of parts of Canada! I'm currently in zone 5A and would love to eventually plant one in the ground, or even just not worry and let it thrive in pots on the patio. Again I've been told different things by all over, some say zone 6 is the lowest, others say 5A, and a few found say 4B. Also, I haven't found an answer to this question either: being indoor in pots they dont actually molt their leaves.. will they still fruit or does flowering only precede a stage of leaf growth via spring?
