Haven't seen anyone growing it but my wife has started stocking it in the kitchen for my low cholesterol diet. I would suspect it's a rather hardy plant if it grows at that altitude. Apparently it can be grown here in AZ too.
It could be challenging to harvest though... check out the wiki on it. Seems like it matures at different times between sections of the plant so it's usually manually harvested.
Very interesting though. Maybe there are types that can be harvested more easily?
