I just finished looking at every page of iris plantfiles at dave's garden and I saw more than I can remember that looked like this.

My first guesses are 'Upper Hand' and 'Raku Rogue', but with my luck it's probably not either.

I'll try to remember others.

I almost forgot. These links might help.

Upper Hand

Raku Rogue

i would ask schrieners,aitkins or the american iris society for help in id'ing this iris.

it may be mariachi music..

Here is a link that might be useful: mariachi music

Thank you for your help but I see that this variety is older than Upper Hand and Raku Rouge, because I have received it in the beginning of 90-ties from Roris or Shreiners garden. I think that the given Mariachi Music theoretically could be similar but the colour is different. But thanks anuway!
