This is a first flowering plant (also have a second plant of this cross, but I think I will have to wait until next year). The hybrid is 50% Ctsm. tenebrosum, 25% Ctsm saccatum & 25% Ctsm. fimbriatum. So far, I have not detected any fragrance.
The first photo was shot with flash. Actually, the flowers are darker than in any of these two photos.
