Bamboo Conne'iseur

D&T, right now the ones with the best cold hardiness are probably gonna be Phyllostachys aureosulcata "Spectabilis" and Ph. bissetii. There are a few more promising ones as well. These will grow in your zone without worries. These have been known to handle very cold temps of around -15 degrees F. The website mentioned needmorebamboo.com is growing bamboo in your state with some pretty good success. When these plants are young they will have everything above ground killed more than likely, but will come back in the spring. Once established, they just might be the only thing around that is still green come winter time.
