Thank you for your interest. For seed availability please see Foundation Seed Stock for the complete listing. The nursery is no longer producing or selling plants, tubers or roots. No sunchokes or groundnuts. Some seeds are offered bulk in season of many of the plants I use to grow. Questions on plants in general or old orders, etc. will not be responded to. The farm continues under my care but the nursery is permanently closed. Thank you. Kenneth Asmus
