I purchased these two iris's from my local Wal-Mart at least 15 years ago. At that time I didn't care about names, but now I'd like to try to find out.
Here are pictures of them. I forgot to measure them when they were in bloom. I believe they were at least 24" to 26" (maybe taller).
Also, the purple/blue one blooms early, at least 3 weeks before the other one. I would put it (the purple/blue) in the "early" bloom category and the other in the "mid to late" bloom category. It's hard to see in these pics, but the purple/blue beard has a bit of yellow/orange way inside.

Someone might be able to ID the top one for you. I can think of at least 10 that would be possible for the purple/white, it will be almost impossible to ID by a photo...sorry, you will have to love it as a beautiful NOID.
