Jerusalem artichoke plants Durham city centre (The Viaduct DH1)

I have 50 surplus Jerusalem artichoke plants which need to be planted out now, 2 ft apart, ideally in front of a hedge or wall as they grow to about 8 ft. They produce tubers which can be dug up from November and are very tasty in soups and stews or roasted. Collect any time. I can leave bags of them on our front doorstep.
