Hi. I admit ignorance when it comes to Bamboo, though I am an avid gardener. I'm wanting to introduce some Bamboo into my garden which already has a good mix of Japanese inspired plant material. I'd like to use the Bamboo in a small area that is (maximum) 3' x 3', Id like it to create a bit of a screen there to a maximum of about 8' high. The reason I have no experience with Bamboo is that people have scared me away from it with the "invasive" line. So, 2 questions, what type of Bamboo should I look for? and, how do I contain it? Does it actually need to be in a container, or is there some form of barrier I can use? Thanks a bunch.
