Rewind June and see if we get some warmer weather at a second attempt? Move somewhere warmer? Grow it in a greenhouse? The other ones you mention will go great guns in weather that is rather cooler than H hookerianus appreciates. Actually you are lucky yours is still alive after last winter.

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
