Carl, I think the pseudacorus is what we call the yellow flag iris. It's considered an invasive weed here. In the more moist area of the state it is really a problem. That is one I definitely don't want to add to my garden (not that it would like it here with the sandy soil and hot dry summers) !
Other than that I don't have any I don't like because I'm so new at this. I'm just happy to have irises blooming. That being said there are a few that are not my favorites, but since most of them have only bloomed once I need to give them a chance to get a nice clump going (if they can) before I decide to thin any of them.
