If you want a good "blue" bamboo that is happier in cooler climates, have a look at some of the newer Borinda species/varieties that have come on the market in the last few years, though some of those died last winter. But they probably won't be quite as remarkable in their culm markings as H hookerianus. Himalayacalamus Hookeriana
