The bearded irises that does not do well in warm temps are the shortest ones, MDB's. I was originally told by my local iris society that they will not grow here. I have around 40 and they grow and bloom but I keep them in pots and I do put them on the north side of the house during the winter so they can get cold for a bit and then in the summer I afford them some shade. I can grow about any of the others with the exception of the pacific coast natives. Louisiana's love the humid heat and my unguicularis is lush and bloomed two weeks ago.
