i have a thin variety, which is useless for anything but looking pretty, i'm also growing giant bamboo, the plan is to use it to make fences and bed edgings, and i'm also growing some for beans and peas .... ok it may be invasive, but that isn't a problem really, i'm growing it cos i want it and it's in the tropical area of my garden.
and at some point hopefully everything in the garden will tie in with the tropical area and be made of bamboo
not much use for this year though, when i'm desperate for some and can't get any anywhere
