Phyllostachys bissetii, clumping or runner
I have a friend in CT that planted this last year and it's doing well. It is 20 feet from his house and I am concerned as to it's invasiveness. He got a little scared this year when he saw it sent a shoot up 2 feet from the main plant.
I have read conflicting things on the web. Some sites say it is clumping, some say it's a runner.
What do you folks think?
Thanks for any opinions offered.
