What a great topic! Interesting to think of a garden that doesn't need division.

Of course peonies and hostas are perfect. There are enough varieties, colors, and sizes of hosta for an entire garden! I can think of two other plants that would work. The first is Baptisia. Lovely plant and very long lived. The second is my all-time favorite perennial, Amsonia Hubrechtii. Blooms blue in the spring, has soft, touch me foliage all summer, and turns brilliant gold in the fall. Mine are 15 years old (pictures below) and I've never done anything but cut them back in late winter and by 1/3 after flowering. That's it. I've never even given them supplemental water - ever. Fabulous plant.
I'm anxious to hear the ideas of others.
