Does anyone have any clue as to which iris this may be? The tag is missing and I've kept good records on what I've traded/purchased during the last 4 years. This is a young plant for my garden, but I can't figure which one it should be. Perhaps it's a mis-marked trade. Perhaps I'm not reading the iris registry descriptions correctly. Anyone have any idea. My guess is 50's from form but I'm not that good as forms yet.
