Chris, a few inches a year translates into a couple of feet a
decade. Most of them have been eradicated now, but all up and
down the East Coast, including in FL, there were estates where
someone had planted th fashionable bamboo -- including clumping
varieties -- in 1920s; and, then after the Crash, they were
abandoned or let go wild. There were places where they literally
had to take the bamboo out with a backhoe and burnoff. So, I'd
have my control system planned BEFORE I planted the bamboo.

The only problem is that a clumping bamboo will not be contained. It
can exert enormous pressure on whatever it is butting up against. A
running bamboo will turn away from the barrier.

Of course, if I left my ginger plants, my bougainvillea, my lawn, my
box hedge, my roses and even my camphor tree abandoned to the decades
it will run rampant as well.

We are discussing reasonable people doing reasonable things with
plants, not what if the world ends tomorrow. For a reasonable person
to plant a clumping bamboo without a barrier is not an unreasonable
thing or even the end of the world.
