My bearded Irises have finished blooming a while ago and now these are starting... Thanks
I can't be sure, but it looks more like a Louisiana Iris to me.
Wow, your garden is so pretty. I love the lime-green around the tree. Whatever it is, it is a lovely iris.
I would say it's a Louisiana also.
Siberian leaves are normally slender, LAs are wider. Hold a leaf up with the sun behind it, and see if you see lines across it. Those are common in water irises, and would denote it's a LA instead of a sib.
I have this and it is a Louisiana,its name is sea wisp.
