Valery, this a lovely photo of a beautiful dwarf iris. I can't wait for mine to blooms. How tall does yours get?

Lynn, Thank you very much! Yes, he is very good, especially the blue beards! The height from memory was quite high. The bush was powerful. Here's a comparison with Little Bit O'Lace's growth:

Thank you for the information, Valery.
I will put it at the back of one of my raised beds. It is in a small pot right now. When it finished blooming, I will move it to one of the beds.
