I'm unwilling to risk it, even planted inside a concrete ring, and even though I have goats and acres between my run and my closest property line.
I am not normally a risk averse person.
It truly is that invasive, almost completely lacking in natural controls, and the rhizomes off the root balls are somehow more destructive than bamboo runners. Besides which, when the plant grows outside its containment, parts of it can take root in fresh ground, and begin a plant outside containment.
Goats are used for control. FIRE and excavation is needed for eradication.
