I'm sorry to say this plant is not A. narcissiflora. It seems to be A. cyatophorum var farreri which often is mistaken for A. nacsiisflora in the seed lists of the clubs. I have more than once got wrong seeds myslef. A. nacesissifloralooks quite different and I don't understand how these two species can get mixed up.
The two species that really looks very much alike are A. narcissiflora and A. insubrucum. I'm really not able to tell them apart, so I don't know if i have both the species or only one of them in my garden.
