I paste here the notes by Tony about this Hybrid: Pinellia 'Polly Spout' is a seedling that Dick Weaver (founder of We-Du Nursery) found in his garden back in the early 1990's...a hybrid of P. tripartita 'Atropurpurea' and P. pedatisecta. Dick named it after the town in NC where We-Du is located. To my knowledge, it is the only sterile form of pinellia, and while it is very vigorous, it doesn't offset very rapidly. It puts on a tremendous floral show all summer and the flowers are most certainly red-flushed, although not as dark as P. tripartita 'Atropurpurea'. I hope this helps.
