That's right, Caroline. There's a list of all of the Saunders hybrids in the Peony Database in the library section, I use this resource a lot!

I've learned the hard way that Saunders peonies don't like damp or shade, moved my Roselette last fall from dry shade to full sun, hoping it'll recover....next to move will be Claudia. It's not quite as shaded but could do with more sun. I'll post pics when/if it blooms this spring, Karen. It's one that hasn't done much of anything in its current location. Since it hasn't actively declined I've not given it the attention it deserves.
