I've never grown these before, but just bought a good sized one and planted it in the ground. It has subsequently lost its leafs. It came from a hot place to my cooler mountain location - but still seldom under 50ºF. Has anybody grown these? How tropical are they - really. I know they are mostly grown in pots, but has anyone seen them in the ground in less than truly tropical places. Or in wetter locations - how do they do?
