One of those really big plants. Difficult to get rid of as the roots travel down a long way. I moved mine and now have it in two places. So make sure it is in the right place the first time!
Imposing looking.... can't grow it here. :)
I grow mine in z6,with little bit of mulch during a winter.Actually I noticed ,colder climate makes it less agressive,so I injoy it`s impressive looks without being concern about my plant beds .
