Eric....in my modest sized pond , I grew it in a pot ....but it smashed through it after a couple of seasons!! Also had some at back of flower bed .......it's a beautiful coloured bamboo....not too tall ( 30" or so )......but a S*D to get rid of!!!!
Not much help to you , but I can give you it's name!!.........to curse! ;)
Pleioblastus variegatus........at least that's the one I grew!! ;D
Best of luck!!
