Greg,
I received Diamond Lake from Schreiners in 2010, along with Coming Storm, Raven Girl, Company Red, Dodger Blue, and Jamaican Dream, from some promotion that they were doing.
I have other irises like Ziggy and Decadence that are also putting out shorter blooms this year. I don't know why they're doing this.
I have to agree that the ID process can be tedious. The good news is that I have the names of all if the irises that I've ever ordered. Unfortunately, tags have been lost, or disintegrated over time.
Thank you all for taking the time to give your input, it's greatly appreciated.
Annette
