Arisaema sikokianum

air-iss-EE-mah si-koe-kee-AY-num Audio

The outside of the spathe is the color of dark chocolate, and the inside, milk white and as smooth as marble. Its hood sweeps up to an arrogant point, exposing its sumptuous white lining and the thick blunt spadix, which is also milk white. This plant produces two leaves per tuber, one leaf with three lobes and one with five. Sometimes they are mottled with silver, which makes them very handsome, at least until the plant goes dormant in summer.
