Deb, you're good! Excellent organizing method. I'll look through my records and see if I can find a name for that little Iris, but you and Bonnie are more than welcome to some rhizomes- it increases well. It doesn't really show any yellow, I that Oregano may be too bright for it, but it sure is a pretty plant! I've never seen it, but it would look gorgeous with another MDB I have that is yellow and white with blue beards!
Bonnie, that's a good idea. I have plucked a bloom and walked around the garden holding it up to other plants, but you're right about sometimes they look better from a distance. Potting it would help seeing it in the big picture.
Celia, I love Peonies too, and I've always thought of Peonies and Irises as the stars of the late spring garden. They offer such a nice contrast of forms- a classic combo
