Some of my most favorite flowers are black, but I don't have any black daylilies. To me, they just aren't black! I think Iris come much closer to a true black, even though many are very dark purple up close. I've got Before the Storm, and it's amazing! I had stunning black Calla Lillies when I lived in CA, but they don't survive here, and I'm not willing to go to the trouble to dig them up. I have a black hollyhock that knocks my socks off! I still don't have any black tulips, but plan on adding some. My neighbor has a bunch, and they really do look totally black.
