Which peony, Itoh, herbaceous, tree, species etc. is the darkest? I've seen that title applies to Chief Black Hawk, Bob & Black Swan.
I'm curious as to what people consider to be the closest to black. I'm hoping there is someone growing at least 2 out of the three. New nominations would be exciting too. I hope this thread isn't already in existence! I'm not trying to choose between the three, just wondering as to colouring since photographs are so tricky and bloom colour varies so much with time of day, growing conditions etc! I expect it is to a degree a matter of opinion.
