    I had the strange experience this year of having Long-Tailed Skippers lay eggs on this plant. It is NOT a host plant for them, but apparently it must seem similar enough to fool them. If you're growing for butterflies, be aware this can happen. If you don't want the Long-Tailed Skippers to die, you might consider planting one of their real host plants nearby, such as butterfly pea.

    That being said, I'm growing this plant in raised beds in a shady side of the yard. I have two and both were easy to establish even in the Florida summer and they have taken to growing up the trellis with ease. I have hosted Polydamas Swallowtail caterpillars on the plant; they can eat it a lot faster than it grows, so be careful! Both got pretty chewed up but rebounded quickly once the caterpillars were gone. I think this is a very worthwhile addition to any butterfly garden, particularly since it can host both the Pipevine and Polydamas Swallowtails.

    Woodland vine. Pipevine Swallowtail females lay their eggs on new growth.
