You guys are great! Thank you for welcoming me into the iris 'assylum', LoL!
The iris I posted is probably only about a foot high, but the bloom is a good size. I don't know the standards for measuring irises, but it's probably about 4" tall and 3" wide? I will try to go out and measure tomorrow and take pictures. It's definitely purple, but it's a very blue-purple, has a very sweet, but light fragrance (I had to get my nose right up to it to smell it).
I don't know if you will see anything in these photos that might help with an ID (as I mentioned, I'm definitely a greenie when it comes to irises!), but hopefully these might help:
