I love this one too, with some misgivings. Lovely blooms are very large and near-white, with good substance. Petals have ruffles and and sepals curl and twist. Apt naming! On the other hand the trifecta of trouble for me is that the scapes are shorter than I would like, the aging blooms make a hung-up mess if one doesn't dead-head, and our rust event of 2018 revealed that the plant is susceptible.
