Thanks everyone, I'm new to irises so I'm not sure what the exact difference is between a flounce, a horn, and a spoon. Though I've seen enough pictures of spaceage irises to have a pretty good idea. I'm interested in the most extremes of any type really. I've had my eye on canary feathers, but I've never seen horned dragonfly before.
Are there any flounces that are larger then Canary Feathers? What you said about horns usually turning into flounces after a certain point makes sense to me Tom.
