Whoops. A purple one snuck into the batch...Iris pseudacorus

In a great batch of Iris pseudacorus (Yellow Flag) there was
one bud with a reddish tint on the bud. Today it revealed that
it is going to be purple.

As the plants are living in my pond, I would imagine this is not
a bearded, it is my understanding bearded Iris cannot function in
a pond setting.

So could anyone tell me what I do have? Is there a purple pseudacorus?

It is not Louisiana, as we have tons of that, and I recently acquired this
little beauty.

Many thanks,
Karen Marie

P.S. No pic, as the camera died this evening. Perhaps tomorrow or the
next day it will bloom.

There are purple or blue flag irises. Iris Versicolor I believe.

Ah, thank you so much!
