perennial pollinator flowers (central Ann Arbor)

We've decided to reclaim our yard from weeds and grass and make it more eco-friendly with native plants. I'm looking for pollinator perennials such as

Purple Coneflower, Echinacea Purpurea
Butterfly Milkweed, Asclepias tuberosa
Rose Milkweed, Asclepias incarnata
Wild Columbine, Aquilegia canadensis

or something along those lines.

If you have an excess of these but don't want to throw them out, I'm happy to dig up a few and give them a new home.

Thanks.
