Very aggressive here Nut but in a cold place they prob wont be. After a year their chunky roots had ventured quite widely. They are good in large pots though. You can divide them every couple of years and flower seems unaffected.
actually, I gave mine away to someone who has a few acres so I might get a piece of two back to plant in pots. Had yellow,,orange and white vwrieties.
hope you appreciated my ginger nut joke back there
