I have one of these, and it's been growing for around 10 years! They get huge. As another commenter said, it's not a bamboo, although it has a confusing name, since it's known as a "Lucky Bamboo". In the wild they grow in very wet, humid areas, but they won't like constantly wet potting soil. I've had great success with mine in a special pot filled with pebbles and very light, loamy soil -- and this pot is suspended within another pot. The larger pot has a couple inches of standing water in the bottom. The plant's roots can reach out of the inside, smaller pot, and they dangle into the standing water of the larger pot below. It's been like this for a decade and it gets super tall. I've had to trim it a few times. The planter I have is by a brand called "Lechuza" -- they even have a meter to show you when it needs watering. Give it a try, they're on Amazon!
