This is probably one of the rarest classes of novelty irises because it is caused by flowers not quite opening. If they open just far enough they present as a magnolia or tulip shaped bloom. We are attempting to develop a list below of Irises with this trait. Please add any that have been missed by commenting in the comment box.
Tall Bearded:'Blue Tulip', 'Pink Magnolia', 'Thurlow Weed'.
