I may have to put that one on my list. I have several dark purple irises (and for a small yard I have too many) that I need to move out to make room for a really dark one. I have Coal Seams and it did not bloom this year. From the photos on here I have seen of its blooms it is another dark purple. I know there is not a truly black iris but.......
