Polygonum bungeanum
Propagation: Seed - sow spring in a cold frame. Germination is usually free and easy. When they are large enough to handle, prick the seedlings out into individual pots and plant them out in the summer if they have reached sufficient size. If not, overwinter them in a cold frame and plant them out the following spring after the last expected frosts.
Cultivation: We have very little information on this species and do not know if it is hardy in Britain, though judging by its native range it should succeed outdoors in most parts of the country. The following notes are based on the general needs of the genus.
Succeeds in an ordinary garden soil[1] but prefers a moisture retentive not too fertile soil in sun or part shade[2]. Repays generous treatment[1].
Plants seem to be immune to the predations of rabbits[3].
Range: E. Asia - China, Japan, Korea.
Habitat: Sands amongst osier beds, near rice field canals, cultivated land etc[4]. Grassy valleys, near fields and roadsides at elevations of 50 - 1700 metres[5].
Edibility: Leaves - raw or cooked[6][7].
Seed - raw or cooked. It is rather small and fiddly to utilize.
