Louisiana Irises are actually a collection of beardless water irises that encompasses five species: Iris hexagona, Iris fulva, Iris brevicaulis, Iris giganticaerulea, Iris nelsonii. They are found naturally in most southern states and even as far north as Ohio. I don’t know exactly which species this is, but I suspect it is the Iris hexagona, which are also natives to Texas. I was given my by another garden friend.
The are that I have my iris in doesn’t stand in water like it used to but they seem to be thriving. They are already blooming and gorgeous this year. I have them in partial shad, but that is probably what is helping them make it through the dry heat of the summer. I will probably need to divide mine this year once they are done blooming.
