"Devil May Care" in my garden has very black petals -- even in strong SoCal daylight -- but the interior is glowing purple with orange beards emanating from that. "Sinister Desire" looks a bit purple in the photo, but to the eye the falls look very black, with just a touch of dark cherry near the edges and a bit more in the standards. "Black Lightning" so far has only given me one funny little water-spotted bloom.
