I grew this last year and to my surprise the flowers opened up polymorphic! They were feathered, doubled, and some that even spiralck!ed down from corolla to the base of the sepal, like a daffodil never completely connecting. I was able to get only 1 viable seed (there were two in the seed pod but one was underdeveloped and never germinated) which I got to sprout. I hope this one comes back true and I will DEFINATELY take pictures this time. Wish me luck!

Ditto to WillowWasp's message.
Mine bloomed aug. 1 and still is.
(in a friend's yard) I didn't think it would really bloom, and boy was I sad that I gave it away. Now I'm scoping out their house for seedpods! An absolute beauty, and a sturdy flower!
