Growth rate of bamboo in pots outdoors

Hi all!

I want to get some bamboo in a pot to block a view and have been looking online but they don't state the growth rate in the pot supplied. I know there are lots of types of bamboo and feel out of my depth in looking but I really like the look of black bamboo. I don't want something that is going to be 20ft tall, maybe something about 6 ft or so and a bit bushy. Is it possible to trim the top of bamboo so it doesn't get too high without damaging it? I have literally no idea with this stuff, I'm a wildflower and herb guy. Can anyone advise?
