Have you considered clumping bamboo? These are species of bamboo, which send up their new shoots right next to the mother plant. Unfortunately the only links I can find to pictures at the moment are commercial nurseries.
Look for the species Bambusa Multiplex, for a starting place.
The American Bamboo Society,
http://www.americanbamboo.org/index.html
has a publication called the "species source list." This lists all of the species known to be available in the US, and several which may not be. It includes
Maximum height, Diameter, and minimum temperature suitable for each species.
Also included, is a listing of dealers in each species.
In a 10ftX15ft area, I would only use a runner in an above ground container.
There is a great deal more to be said about bamboo, but this should get you started in the right direction.
