We were lucky to recently take a photo of a Pipevine Swallowtail Butterfly laying eggs on its host plant, California Pipevine.

This is a plant in our Treasure island Nursery that we salvaged from a construction zone on Yerba Buena Island. When we dug these plants up, there were caterpillars all over them. We’ve been hoping that the butterflies would find our plants, and it looks like they have!

There are only a few wild pipevine populations left in San Francisco. This butterfly can only lay its eggs on this plant, so by saving this plant, we are saving the butterfly.
