There are only two aristolochia in the mid-Atlantic region that are able to provide food for the pipevine swallowtail butterfly larvae and this is one of them (the other is A. serpentaria.) A native perennial vine that has large (up to 12″), overlapping heart-shaped leaves. Unusual, 2”-long, yellow-burgundy flowers resemble smoking pipes. Quickly provides dense cover for porches, trellises, fences, walls, and more. Twining stems need a sturdy support to grow on.
