I was thinking of getting one of these next year, but haven't heard much about it. I bought the common ones this year that suppose survive here like nuda, aureosulcata, rubromarginata,and bissetti. I've read in places where some say its one of the cold-hardiest and other places that list it down to 0 degrees. Does any know whether this specific species of bamboo can survive in winters that often get down to -15. Thanks for any input.
