We got this exotic pipevine from our local nursery. It's a new item for them. An employee said it attracted swallowtails.
The issue is that some members of this genus are toxic to larvae of Pipevine swallowtails. But I can't find information about this species.
Anyone know about A. littorals? We already grow California Dutchman's Pipe, and see lots of caterpillars, so if nothing else, we could run an experiment.
Aristolochia is a large plant genus with over 500 species that is the namesake (type genus) of the family (Aristolochiaceae). Its members are commonly known as birthworts, pipevines or Dutchman's pipes and are widespread and occur in the most diverse climates. Some species, like A. utriformis and A. westlandii, are threatened with extinction.
