Growing Phyllostachys bissetii in Kingston...hardier than Yellow-groove (& Black Bamboo). Find it's leaf and stem hardiness is a combo of temperature-duration. A couple of weeks of -10C lows w/o a thaw is as damaging as one night of -26C. It's rarely stayed evergreen over 15 years but has been stem hardy about 1/2 of its winters. I maintain it to a 10'x10' clump however it now throws up culms 30' away...if I didn't control it by breaking off culms, it would be a giant in very short order!
If the old culms make it through the winter, about 15' for the new culms. If it's a winterkill year, ~10'. Don't really know what 2+ back-to-back survival years will do...maybe 20'+?

That's amazing! How tall does it get for you?
