Bamboo comes in many, many varieties. Running bamboo is indeed invasive, whereas clumping bamboo confines itself to the planting areas. To contain running bamboo, one needs to surround the area with at least an 18 mil thick plastic 2-3 ft down and 3 inches above the ground to successfully ‘stop’ the runners. In the past few years, growers have offered winter/mountain bamboo which can be grown in the 5-6-7 zones.
Thanks for the info.
