I googled Siberian Iris and WOW there are tons of different varieties! I haven't found one exactly like this, but they are so similar, I think you're right Jessi! Thanks!!!!
Found this link with several of the varieties, but none of these look quite right.

But it says there are only a few of the varieties out there. Wow, I had no idea!
