Is there a delicate, dwarf, manageable bamboo that I can plant in front of a small patio wall?
The clump forming as opposed to running bamboos are the best in your situation. Try Fargesia nitida. See also Paul Whittaker’s book, Hardy Bamboos : Taming the Dragon (Timber Press, 2005, available in the McLean Library). Whittaker lists suggested dwarf and groundcover bamboos.
