What are your favorite Moist Soil plants?

I have wet heavy clay in one spot in my yard. It's a sunny location except for the area directly underneath a weeping willow. I'm looking for plants that like such moist or even wet conditions. So far, all I have planted in this area are Japanese iris and they seem to love it. Can anyone recommend anything out of the ordinary? I've seen the plant lists for this sort of wet soil and I'd like more variety than what I've seen so far. ------------------------------------------------- Has anyone ever grown the Vial's Primrose that Park's Seed Co. is offering for sale this year? It's supposed to like moist or even wet soils. Thanks!
