Jenni,
I agree with the other mom about the choices. I love my spirea, very reliable for a splash of color especially if you deadhead the spent blooms. sedum is also nice - just added 5 new ones to my yard. There are some very nice ornamental grasses that stay nice and compact and are colorful to boot! I also LOVE LOVE LOVE my knockout roses! very easy to care for and bloom continuously!
If you have a bunny problem I would stay away from certain things though... they see any bulbs as buried food - they dug up all my tulips (200!!) and eat my oriental lilies before they get 8 inches high. And they do for the most part stay away from my stella d'oro daylilys - they eat the leaves but they dont destroy them. and those rebloom if you deadhead as well.
