Depends on how you define it. It spreads by running rhizomes, but that's it basically for propagation. It's not truly invasive like those that also propagate from seeds or easily from cuttings. In my zone I don't think it'll be too much to contain. I'll probably get top kill of the canes every winter. Bamboo doesn't like that. It'd probably go wild in your neighborhood though. This isn't quite like that nasty japanese knotweed either.
