This is great, because I have been looking for info on these a long time. Can anyone please give Zone requirements, and other other basic info as to where they will do well? I have already struggled to keep a bunch of not-quite-tropical plants alive, and at this time am not looking for more. Last I read, it sounded like these are more temperate, really. I live in a perpetually humid, sea-level Zone 11, and wonder if this would really work out for me without a lot of extra care, which I definitely don't have the time for now...
