The Louisiana looks violet_ish on my screen so here are the names of some tailored, non-overlapping petals, narrow signal ones. (Does the signal stay thin or does it widen in the hidden area?).
Black Gamecock
Chuck
Jeri
Puttytat
Vinicolor

The bearded looks as tho a flash went off. If so the color has been affected. A picture in daylight with raindrops shaken off would be helpful. Very pretty iris. 2 different side views help show the form. And if it fades substantially, pics of each day. Any info on possible age is helpful.

Thanks irisgal. The signal stays thin.

I managed to take this picture yesterday before the blooms wilted.

I forgot to say the age. I got it 2 years ago and it bloomed for the first time this year.

It definitely looks like yours irisgal, thanks!

Don't put RM as the name...before you do..get a rhizome of RM from a reliable source and grow it side by side to compare bloom time, height, color, etc...You want to make sure its RM before you pass it on as such... Yours doesnt seem have the white area below the beards that RM has..

That's a good idea. I'll look for a RM rhizome next year so I can compare them. Thanks littlebit_gw.

Mine does look similar Mary. I got mine from a lady in Louisiana that got them for her mother-in-law. Well her MIL didn't want them she dug them up and forgot where she ordered them from and the name of the irises.

I am so bummed--I separated what I thought was only 3 clumps of Springhouse Iris because it was crowded and also to give a tuber to a friend, and this year I got one tall white iris and NO buds on the rest! My Springhouse was so lovely!! I will let it rest until next year (do you cut yours back if they interfere with later flowers in the bed?) and hope separation shock was all it was.

Mary I'm a novice when it comes to irises, hopefully someone with more experience will chime in? That's so disappointing that the one that bloomed was a tall white iris. I haven't separated any of mine yet, but it's probably time?

The only time I cut back is when I am digging and dividing them. Healthy foliage helps feed them for next yrs bloom.. Now if I do have one that might interfere with another plant. I just trim what is in the way, not the whole plant..
As for yours not blooming..sometimes they do take a yr off before they bloom again...As far as the white one blooming..more than likely Springhouse was crowding the white one out and moving it allowed the white one to shine..

I've had a 'weed' show up, some years back. Weed only because I didn't plant it. I've been calling it my "Miniature Iris".. I can't find anything online that describes this 'weed'. Local gardeners have no idea.
The leaves look exactly like a miniature Iris. There's no corm, but the base is 'bulbous'. Blooms are not at all like any bearded or Siberian Iris I have.
They are about ~4-5" high. Very slow growing.
Those are NORMAL sized bricks (~6-7").

Bob, does yours look like this when open?

By Jove Irisgal! I think you've got it!! ;-)
That's quite a large number of species for that Genus!
The one pictured is difficult to see the leaves. Some appear to be stems.
The ones in my garden don't have anything other than 'iris-like' leaves, the flowers appear at the tip of a leaf, no different-looking stem for the flower.

Thanks for the clue, I now have a Genus for my "Miniature Iris"

A Google search on the Genus name yields many 'hits', and to best part - it IS in the Iris family!
