Just bloomed. The man who sold it to me said it's a very large, dark variety. I don't have any experience with this flower, but the flower is quite dark, I like it. (I took the photo in sunlight, didn't doctor anything.) It's my first blooming of this, and I suspect I may have a division of the plant, since I'm not seeing any previous blooms, but the guy knew how it flowers. No clonal name.
Oh, and to get it to flower, I fried it in the sun this summer. This guy likes sunlight.
