Arisaema dahaiense is a species native to the Gaoligong Shan region of Western Yunnan, China. It looks similar Arisaema galeatum & is easy to grow in my woodland garden in well-drained soil in semi-shade. The very large trifoliate leaves reach around 60cm high & shelter the hooded dark purple & cream lined spathe with its long spadix. These are flowering size & will become larger every year.
