There are still many undiscovered (in the west) perennial edibles in the Far East. I’m therefore now concentrating mainly on that area in this quest. This spring I will travel for 3 weeks in Japan as part of this work. Another “country” with a rich diversity of food plants is Korea. With help from my Norwegian / Korean friend Misoni Sandvik whom I mention in my book, and who is on her own quest to find and grow wild herbs she remembers foraging when she was a child in South Korea, I’ve received two books from Korea today entitled “The Wild Greens of Korea” and “The Medicinal Herb of Korea”. There’s often a diffuse boundary between food and medicine in Korea, so the second book is also relevant, including plants like Aralia cordata (Udo)!
