Calystegia hederacea
Propagation: Seed - sow spring in a cold frame in a free draining compost and only just cover. The seed usually germinates in 1 - 3 months at 15°c[1]. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in a cold frame 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 early spring whilst dormant[2].
Cultivation: Easily grown in ordinary garden soil in a sunny position, but plants are apt to become invasive[3][2].
Nearly all taxa in Calystegia intergrade geographically into neighboring taxa with the exception of the widespread coastal species, C. soldanella (Linnaeus) R. Brown. It is impossible to draw clearly defined specific limits, and intermediate forms are always found where two taxa approximate geographically[4].
Range: E. Asia - Japan, Korea, Manchuria.
Habitat: Sunny grassy places and thickets in lowland and hills of C. and S. Japan[5].
Edibility: Root - cooked[6][7], then washed and steamed. Considered to be very nutritious, it is rich in starch and sugar but it should not be eaten regularly[8].
Medicinal: The seed is simmered in water as a diuretic to stimulate kidney secretions[9].
Pollinators: Bees, lepidoptera
Soil: Can grow in light, medium, and heavy soils.
Flower Type: Hermaphrodite
Known Hazards: Although no reports of toxicity have been seen for this species, at least some, if not all members of this genus are purgative[10], some caution is advised.
