Zone 10, 25 foot maximum, least aggressive running bamboo
I have been searching the forums and often see one genus or another of running bamboo referred to as "a very aggressive runner."
Is there a running bamboo which is not considered an aggressive runner?
I live in Zone 10, SoCal, and am looking for something which will grow to 25 feet within a narrow area. There will be a rhizome barrier, but I'd still be interested to hear of something which would be less invasive.
As of now, I am strongly considering S. Fastuosa, Phyllostachys aureosulcata Spectabilis, or Phyllostachys Vivax Aureocaulis.
