I agree with bullthistle, be careful where you plant this. I have some of this in a bed that has two other beds as neighbors, the house as a third side and concrete stairs as the fourth. Even though it is relatively contained it is a yearly task to keep it from the adjacent beds. The side with the stairs is pretty easy to maintain, whatever hangs over gets cut off. But the side next to the house is a problem. I have to trim it at least once a year. It evens tries to grow under the vinyl siding.
Choose a location where it is confined and prune it yearly and it is manageable if a bit aggressive. Oh, and don't let it get into your lawn.
