Arisaema iyoanum var. nakaianum is one of the rarest and most dramatic of the Japanese native cobra lilies...found only along riverbanks in Japan's Shikoku Province. The 3' tall single black-blotched stalk is topped with a single horseshoe-shaped green leaf with 9-11 leaflets. The jack-in-the-pulpit-like spathe is dark black with pink-to-green vertical striping. Inside the flower (spathe) sits a club-like green spadix with black freckles...each seedling is slightly different. The shape of the inflorescence is very reminiscent of the character Mushmouth on the Fat Albert cartoons.
