Propagation: Seed - sow spring in a cold frame. When they are large enough to handle, prick the seedlings out into individual pots and plant them out in the summer.
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 should succeed outdoors in many parts of this country. The following notes are based on the general needs of the genus.
Succeeds in most soils but prefers a deep fertile moderately heavy soil that is humus-rich, moisture-retentive but well-drained and a position in full-sun or part shade[1].
Range: E. Asia - Japan.
Habitat: Wet meadows in lowland all over Japan[2].
Edibility: Leaves - cooked[3][4].
Seed - cooked. Used to make a gruel[3][4].
Medicinal: The root is anticoagulant, antipruritic, antipyretic, diuretic, laxative[5][6].
Usage: Although no specific mention has been made for this species, dark green to brown and dark grey dyes can be obtained from the roots of many species in this genus, They do not need a mordant[7].
There is a report that the plant is used to kill bugs, but no details are given[5][6].
Pollinators: Wind
Soil: Can grow in light, medium, and heavy soils.
Flower Type: Hermaphrodite
Known Hazards: Plants can contain quite high levels of oxalic acid, which is what gives the leaves of many members of this genus an acid-lemon flavour. Perfectly alright in small quantities, the leaves should not be eaten in large amounts since the oxalic acid can lock-
Also Known As: R. madaio. Makino.
