Although they can take a few years to reach maturity depending on where you are, this is a plant that we don't plant around our area. In Tennessee this becomes very invasive very fast. The warmer your climate, the faster they spread. In my area they take over everything and are almost impossible to keep under control. It is best to do them in container here.
