Hey thanks for input. That sounds like I might not have much difficulty growing outside then. We get considerably less sunlight than most places is the only real problem. And I truly do mean Considerably. Less. Sunlight.
I have mine outside right now, it doesn't seem to be dying or anything bad like that. The weather's not too bad either so if they can withstand snow for four months of the year I should be fine.
It's good to hear perspective from someone who lives within their natural range. I really do hope to see these in the wild someday soon. I'm sure I've driven past some habitat before by now on road trips.
