Hi Natalie,
Rozella is tough to top!
Here's a few I've had success with:
Pink Pom Pom (also a Reath intro, like Rozella)
Pink Pearl (Sass) - quite short and compact
Better Times (Franklin)
Sky Dance (Seidl/Bremer)
Juliska (Seidl/Bremer) - Very tall and different. Stems might lean sometimes but never hit the ground.
If you can accept a peony that produces some very fluffly semi double flowers in addition to full doubles, Kathy's Touch has an awesome flower form and great stems.
