I'm looking for cold hardy and very tall bamboo, fast growing as well and striped. I would like to use it for privacy, sort of a privacy fence. I saw this particular vivax bamboo and it's definitely one i'd love to have. Black Bamboo is another i'd love to have but am not sure if it will grow here in zone 7a. Anyway if anyone has any of these bamboo's and would like to trade please let me know. I have just gotten done updating my exchange list so take a look and i hope you find something you like. :) thanks in advance! (here is a picture of the striped vivax i'd love to have)
