Not sure if I did this right, but I am from Minnesota and I too wanted ssome in my yard. Last Sept. I was back "home" and my sister in law gve me some roots. They were in some dirt on the plane and we did not get them in the ground or 5 days. After 32-4 weeks I got 3-5 stalks on each root that I planted. They die off with winter but right now they have healthy stalks an the leaves are getting broader. I did plant them in some sunny areas with no soil prep and no fertilizers added. Hope this helps.
