This came to me from Chen Yi in China a long time ago. I have it labeled as Arisaema biauriculatum but cant find any photos that look anything near to it & the name is a bit suspect as well. It eventually gets fairly tall,my adult plants are around 1m plus high. It has a whitish tint to it with the green & the stem is very nice. Its not A, tortuosum, it is very different from that. These are all offsets not flowering size yet, not sure how far away, probably a couple of years. If anyone can ID it...please tell.
