Arisaema intermedium is closely related to A. costatum and A. speciosum. It has green, sometimes purple-flushed, spathes with subtle white striping. Its most intriguing characteristic is the long thread-like spadix appendage which usually gets caught on the emerging leaf and hangs twisted from the leaflets. If you unwind this appendage it can often be more than three feet long! Easy to grow in part shade and light compost rich in humus. From Kashmir, India, Nepal, Sikkim and Bhutan.
