I grow English Charm, which also smells like cat pee. Similar colors, too. I'd call that a peach amoena. It's not at all pink to my eyes. Some pink irises are a very warm pink, but that's peach!

Thank you for the reply! It's similar to your Iris but has less ruffles on the falls . It must have some of the same genetics to smell like that. At first I thought it was sprayed by a cat. Then, as each new flower unfurled, I checked for scent and it was not the sweet aroma I thought I would find!

Peach it is!

My "Blazing Sunrise" looks similar.

Not much fragrance.

Summer snow ???

Invitation is another one!

'Invitation' looks closer due to the falls not being ruffled.
I read somewhere that 'Invitation' is a rebloomer, but in three years here my Iris has not rebloomed.

I cannot find anything on 'Summer Snow'.

Thank you for the suggestions. It's the only Iris I've grown that has a scent that is unpleasant.

Here is where I found it! Just scroll down the left column to the name.
