I bought this plant 4 years ago because I thought it looked interesting. It quickly became one of my favorite plants of all time and one I would not do without. It is slow to emerge in the spring but seems to grow in leaps and bounds overnight once it gets going. It has the most beautiful white plumes and they last and last all summer long. Even when they start to fade, they are are still gorgeous. I love tall plants and this one fits the bill if you want something tall and bushy as well as low maintenance. I leave the stems intact over the winter and when I cut them down in the spring, they are hollow and super easy to cut back. This is a non-invastive Persicaria, mine has not seeded at all (although I wouldn't mind if it did). Very easy, lovely plant, recommend to everyone I know.
