A beautiful surprise plant. We had no idea it could be so pretty until we had a picture blowup. Great plant.

These really make a show in late summer, early fall. Yes, they do multiply and will take over a bed if you let them. Take care, but they are worth it. MN4

Got 6 of these in a trade a few years ago. Didn't do much the first year or the second. I kept moving them around the yard till I found a place they liked. Unfortunately I didn't know what they were or how tall they got until last spring. They finally started growing and bloomed. Very pretty but location all wrong for something that tall. Decided I would plant them against soemthing to really show their height and beauty off this spring. To my amazement, my 6 little plants have mutliplied into around 600 and the more I dig, the more I get. LOL
