Aristolochia macrophylla has luxurient heart shaped foliage. It is a deciduous, woody, climbing vine that is an eastern American native which typically occurs in the wild in rich, moist woods and along streams. The deep burgundy flowers are cloaked beneath the leaves and although the flowers make interesting conversation pieces, they are usually hidden by the dense foliage. A great plant for growing on trellises or a garden tripod or tuteur. A host plant for the pipevine swallowtail larvae (see additional photos). The vine will grow nicely in part shade or full sun, and was used in victorian days to shield porches from the hot midday sun. It generally does not become overly aggressive, and responds well to pruning.
This plant is moderately resistant to damage from deer. As stated, it is a host plant for the Pipevine Swallowtail butterfly and plays an important role in the life of native Pipevine Swallowtail butterflies. The flowers provide nectar for the butterflies, and the leaves are an important food source for the caterpillars. The vigorous growth of this vine makes it easy to share the leaves with these beautiful insects.
Easily grown in average, medium, well-drained soil in full sun to part shade. Prefers rich, moist soil. Intolerant of dry soils. Cut back in late winter to control growth, if need be.
