Aristolochia macrophylla
Also called Pipe vine, Dutchman's pipe, Birthwort Family, Dutchman's Pipe Family, Birthworts, Birthwort And Pipevine Family
Aristolochia macrophylla is a fast-growing, woody perennial vine native to the eastern United States and southeastern Canada, grown for its large heart-shaped leaves and as a host plant for the pipevine swallowtail. Give it a sturdy support, sun or part shade, and moist soil.
Aristolochia macrophylla, Dutchman's pipe or pipevine, is a perennial vine native to the eastern United States. A. macrophylla belongs to the plant family Aristolochiaceae and is found primarily along the Cumberland Mountains and Blue Ridge Mountains in the eastern portion of the United States, as well as Ontario, Canada. This species of plant has received considerable attention in the past few decades for the discovery of a potent compound called aristolochic acid, which has been the focus of debate due its harmful side effects.
Aside from its decorative qualities, owing to its large leaves and dense growth, it is cultivated in gardens because it is a larval host for the pipevine swallowtail, Battus philenor.
A. macrophylla has a relatively wide distribution. It is found from Maine to Alabama, and reaches all the way to Georgia, Tennessee and Kansas. The plant species generally ranges from the Eastern region of the United States up to Michigan, with the exception of Ohio, Indiana and Illinois, and reaches the southeast up until Florida where the presence of this species comes to an abrupt halt. It is also common in Mississippi and Alabama all the way up north to Maine and Ontario, Canada. A. macrophylla is considered to be a threatened species in Maryland. Although the species is not endangered yet, the pipevine could be well on its way to endangerment if measures are not taken to protect this species from the negative consequences of deforestation and other aspects of human disturbance.
