In your zone, the best way to prepare these seeds will be to let nature do it. They are classified as invasive and have no problems starting outdoors, after a winter cold stratification.
Just plant in a container once the weather starts to stay colder, and allow the winter weather to work its magic.
I would avoid planting in ground, since they are known to become highly invasive. Consult your local agricultural services for information on any restrictions with planting these.
