Here are some of my best black irises that seem to thrive here. They at least survive the bitter cold winters
and scorching summers!
The late Sterling Innerst would most likely be my pick for black iris introductions. And I do not intend to belittle anyone
else in the business, but I can only speak for what survives, grows, blooms and looks attractive in the garden. And his irises
are some of the finest I've grown.
The top ones are my pick as the best in 'black' irises. I can't leave out Schreiners' Hello Darkness as a good, good iris: It
is my #3 choice, and I would always keep it around. It's a keeper for Sure! And Before The Storm still resides here too.
These are my personal choices; and Im sure different gardeners will have a much different take on 'black' irises.
