Daisy, I only acquired Berserk last year, and I don't know if it will bloom this year. It seems to be growing well, though.
I have Hysteria and like it a lot. I'm not sure I'd describe the beards as "vivid tangerine," they seem more dull orange maybe? I like fragrance, and this iris smells like licorice to me.
I'm don't know much about what makes a good iris, but the flowers on Hysteria seem to have substance, and the plant has grown well for me, and I don't recall the stalks ever flopping over.
If I get blooms on Berserk, I'll try to remember to report on them.
