Woolly Dutchman's Pipe - Aristolochia tomentosa
Woolly Dutchman's pipe is not as commonly available for purchase as Dutchman's pipe (Aristolochia macrophylla) but for gardeners who wish to attract Pipevine Swallowtail butterflies with a 
plant species that is native to their region, it is worth seeking out. The native range of both plants overlap somewhat but wooly Dutchman's pipe's native range extends further west through the more central portions of the United States.
Able to tolerate shade, woolly Dutchman's pipe is a vine that requires support as well as moderate moisture. As its name suggests, woolly Dutchman's pipe is covered with short hairs on the undersides of the leave, flowers, and young stems that give the plant a fuzzy appearance when viewed at close range.
