Attracting Butterflies

Two of my favorite butterflies are the eastern tiger swallowtail and zebra longwing, but I can't seem to attract them to my yard.

I keep thinking, if I plant it, they will come. But I have tulip trees, willow trees and passionvines, and still no butterflies. Can you offer more tips?

Tom: Tiger swallowtails will only visit your yard if they are common in the area. You are near the edge of their range, but if you see them in your area, you should be able to attract them.

Planting plenty of nectar plants will catch the eye of strays. In particular, try cottonwood, sweet bay and cherry.

For zebra longwings, keep using native passionvines, as they will work the best. These butterflies prefer shaded habitat, so try growing this vine up a tree.

Good luck. I hope your persistence pays off!
