Hope I didn't make a Boo-Boo getting this BOO)
I have just ordered Phyllostachys Atrovaginata. The big 3+ inch culm (eventually) timber bamboo. I have a raised area with soggy soil and the Phyll. Atro seems perfect. I am definitely going to use barrier. If I try a container, I think it will fall over and burst it's sides quickly. I have a book that says it can handle boggy soil. My big worry is with the giant culms and controlling it. It will have a large area to colonize for a while, but is it aggressive in zone 6? I am over-reacting probably, right? It said zone 5, so I'm sure it will survive zone 6.
