if you're in charlotte the summers will be wayyyy too hot for it. The only hope it'll have is if you have cool water running over the roots nearly constantly.
Waaaaaay too hot?
How inaccurate is this graph?
About 10-15 degrees too low during the day and night at least during the summer months
Ouch, that is inaccurate.
I meant to mention that I have read of many keeping them alive on windowsills, as they are tolerant of moderate to maybe even heavy shade.
I'd be very happy to grow at the temperatures shown on the graph, those are within my experience.
