Liatris (spp) is great too

This is a list for Michigan, but a lot of the plants will work here. List by plant and type of butterflies.

plain-not palin

palin...not palin

salpiglossis, rugosa roses (or any scented rose with only one, 2 rows of petals.), I see them around zinnias, and jewelweed also. And don't forget palin old red and white clover

Thank you everyone! This gives me some great ideas. I can't wait to get started.

This is a great plant for butterflies. It is always covered with them when in bloom.
Buttonbush. It attracts the big ones!

Also New Jersey Tea

The trick is to have a mix of plants that bloom throughout the season early spring to late fall. Also, different size flowers attract different butterflies, moths, and bees. One thing that is cool is checking the garden out at night. There are so many moths.

Swallowtails love rue, which is sold at many farmers markets this time of year.
