Could be "Gudrun".

Well, the pictures & descriptions online all say that Gudrun is "massive" & "pure white".

This one is just a normal-sized flower with a tinge of a lemonade-ish cast, & there's a kind of glitter or shimmer to the petals.

Thanks.

grannymarsh, you're right!

They were only about 25" tall last year, & the flowers were small.

I separated them, got the hard-packed clay soil worked out of their roots, & planted them in reasonable garden areas.

They're blooming like maniacs right now, nearly 4' tall, huge flowers, just gorgeous!

& WorldIris mentions "gold dust" on the petals, which, I guess, is what I was calling a lemonade coloration & shimmer & why the "pure white" threw me.

Thanks!

On second thought I don't think yours is Gundrun, Somehow the form isn't quite right. The only positive way for most of us to ID it is to pruchase said cultivar from a reputable grower and plant it next to the NOID. I suspect my white NOID is Gudrun and as soon as I find a source I will buy/plant one next to this one. My bloom is jumbo, at least 6 inches tall.

Sylviatexas: the form of the first iris, in the first picture on this thread, makes me think it is a pretty old one. There was a man who used to post a lot in this iris forum, lives in Washington State, and he helped me identify a lot of my old ones. Wonder where he is now and what he is up to?
