Cynanchum japonicum
Propagation: Seed - sow spring in the greenhouse. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for at least their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts.
Division in spring.
Cultivation: We have very little information on this species and do not know if it will be hardy in Britain, though judging by its native range it could succeed outdoors in many parts of this country. It probably does not have any special cultivation requirements and will probably succeed in most soils in a sunny position[K].
Range: E. Asia - Japan.
Habitat: Thickets and grassy slopes near seashores, C. and S. Japan[1].
Medicinal: The plant is antitussive and expectorant[2]. (The part of the plant used is not specified.) A decoction is used in the treatment of lung congestion, fullness of chest and sides, shortness of breath and rasping throat[2].
Pollinators: Insects
Soil: Can grow in light, medium, and heavy soils.
Flower Type: Hermaphrodite
Known Hazards: There are some reports of toxins in this genus[3].
Also Known As: C. grayanum. Vincetoxicum japonicum.
