Hi there everyone. I need suggestions for a large container that will be bushy about 4-7 or 8 feet up to screen a bathroom window. I can't plant anything in the ground there because it is where all the pipes enter the house and drainage system is there as well.

I was thinking of trying Buddah's Belly Bamboo Does anyone know if it stays bushy at least for a few years in a large container?

I'd love to hear your suggestions. I would prefer a tall shrub or tree that stays dense in a container and something that is fairly common so it reasonably priced to buy in a large size. Thanks!
