Blue flags are common in the wild here, and I am pretty familiar with them. I think these "market" iris are what they call "Dutch Iris" - technically Iris × hollandica - a hybrid. Yellow flags are European, though they have escaped gardens and spread, while Blue flags are native in the US.
From Wikipedia:
Iris × hollandica, commonly known as the Dutch iris, is a hybrid iris developed from species native to Portugal, Spain and North Africa (Iris tingitana × Iris xiphium).
The wild ones are the blue form, I think, but many colors have been bred for the florist trade.
Siberian iris - Iris sibirica - is different, although it too has been bred into many color forms.

Thanks, Linda. It came out pretty good. I have just started experimenting with stacking. That one is 57 shots stacked. I got an old rail for free, and it works great.
