Sheryl: I bet you will indeed see some Spicebush Swallowtails in your garden this year!
Linda: We have lots of Cinnamomun camphora (Camphor Trees):
Camphor Tree (Cinnamomum camphora) around here and my Florida Butterfly book says that is one of their host plants. How cool that you got a free caterpillar with your plant! I just looked up the Spicebush in the Plant Database:
