I can trade finger root for it! The C. Aeroginosa. I do have the mango ginger too. Anyone have black turmeric? Tried growing it but the rhizomes rotted. Will trade! Have zedoary ginger, K galangal, mango ginger, finger root, lesser and greater galangal, false cardamom, Jamaican spicy ginger, shampoo ginger, regular turmeric and ginger, amphomorphous galangal. Not all are tradable right now but for the aeroginosa or black turmeric I'll see what I can do. Think blk turmeric is C. paviflora/paviolina??? Could be wrong. Its intensely black/purple. What aeriginosa you have? The blue or lime colored?
