So I'm thinking of planting Black Bamboo as a privacy screen in my backyard. I would like to contain them in about an area 15 feet long but only about a foot wide, does this sound plausible to anyone that knows about black bamboo out there? Also, how tall would they grow? How long do they take to get to full heigth? I would like to see them get to about 15 and stop really, maybe 20 or 25 but no taller.
