It's a walking iris. People call it the Apostle Plant sometimes, and it grows well in Louisiana, hence the confusion. I believe it is native to South America.

Wait until the pups grow roots, then detach them from the mother plant and plant in regular garden soil. Don't cut off the bloom stalks after the first bloom, since they keep blooming from the same stalk.

I'm not sure about water requirements, but you might try a google search for Apostle Plant.

My iris is long done blooming. It bloomed for like a month. Its first time ever. Next year, now that I know what it is, and can find out how to take care of it, maybe I will get a mass of blooms for months! I only have 1 stem of blooms and got about 5 flowers, one after another. Now I am just waiting for that pup to throw out roots,...if that is what it does. Then I can pot up the mother plant and put it in more shade and better soil. It is already growing like a monster now, so if it gets better conditions, it will go crazy. Boy, one rhizome cost a lot! I have a nice expensive iris 'clump'!

Indeed- I was thinking the same thing- that's a pricey plant. If it's growing well now, I wouldn't move it into too much shade.
