Manchurian Pipevine Aristolochia manshuriensis - Chinese pipevine

Chinese Aristolochia, Aristolochia manshuriensis

Winter hardy 5-9.

Aristolochia manshuriensis , Manchurian Pipevine , Where winter hardy, it needs a trellis, arbor or other structure on which to grow. Also can be grown in containers.
The East Asian equivalent of the American Dutchman’s pipe (or pipevine, A. macrophylla) has only recently been grown in Finland. If you find the rich foliage of the American species attractive, then you’ll find the even larger-leafed Asian species an interesting alternative. The two species also differ in flower colour: the pipe-shaped flowers of the Asian species are yellow-green, but the American’s are red-brown. However in both cases they are mainly hidden by the foliage. Both species are excellent for covering pergolas, arches or gateways as long as the landscape isn’t too open.

MORE DETAILS
Aristolochia manshuriensis, commonly called Manchurian pipevine, is a deciduous, woody, twining climber that produces unusual apetalous flowers, each of which features a calyx which resembles a dutchman’s pipe suspended on a thin stalk. It is native to mixed forests in Korea, eastern Siberia and northeastern China including the area formerly known as Manchuria.

This vine will typically grow to as much as 15-20’ long (to 8' in one growing season). Large, leathery, orbicular, cordate, palmately-veined, light green leaves (to 11" x 11") are abaxilly covered with white hairs. Each creamy white flower is densely mottled with yellow-green and features a contrasting 3-lobed bronze-red limb at the apex of the corolla-like calyx. Flowers bloom singly or in pairs from the leaf axils in June-July. Each flower acts as a flytrap for insects (flowers are primarily pollinated by flies) that are lured by potent fragrance into entering the calyx where they are dusted with pollen before leaving. Flowers give way to cylindrical dehiscent seed capsules (to 4" long) containing winged seeds which ripen in late summer. Capsules open basipetally when ripe, releasing the seed for distribution by wind.
Where winter hardy, it needs a trellis, arbor or other structure on which to grow. Also can be grown in containers.

Scarification: Soak in water, let stand in water for 24 hours.
Stratification: cold stratify for 90 days.
Germination: sow seed 1/4" deep, tamp the soil, mulch the seed bed.
Other: fall sowing in mulched beds is prefered to artificial stratification.
