If you have a confined space, you should look for the species that we call compact . Depends on the species and if you want a dense hedge or if you want to see each plant individually. Sure, they belong to you and you can do whatever you want with them. A lot of people think bamboo is easy to propagate. This has not always been our experience.
Some species are easier than others.
Some species are really baffling. While it is not exactly rocket science, it is not totally simplistic either. You have to get the right material, at the right time and be able to keep it under the right conditions. All of these aspects vary enormously from species to species. Also, some plants, especially some of the more interesting cultivars, may lose their particularly attractive characteristics.
