Help!

I like variegated liriope.

Asters are OK. At least they're colorful.

But aconitum? Chelone? Trycertis? Callicarpa? Honestly, not so much.

By the time the first three begin to flower in the fall, their foliage is already so ratty looking that no matter how beautiful the flower, the overall effect is less than pleasing.

And, yes, callicarpa's purple berries are vibrant and beautiful, but you practically have to have your nose stuck in the shrub before you really notice them.

So what are my alternatives for the shady fall border? Really, I'm pretty desperate here. Am I going to have to resort to impatiens?
