Vanozzi! I too love Japanese iris (and Louisiana's too). They are so graceful in form. I just planted several last summer. If they do well, I plan on increasing their numbers! There are some other members on this site that have beautiful Japanese iris. The member, pirl, has posted many pictures of ones in her garden that have made me drool.
I have one old timer clump of Japanese iris that are common here in North Carolina. I will have to post pictures when I get to my home computer.
