Propagation
Seed - best sown as soon as it is ripe in the autumn in a cold frame[7]. It can be slow to germinate. Stored seed requires 6 months warm followed by 3 months cold stratification[3] and can be very slow to germinate[4]. Prick out the seedlings into individual pots when they are large enough to handle and grow them on in light shade in a cold frame or greenhouse for at least the first winter. Plant out in late spring or early summer. Cuttings of half-ripe wood, July/August in a frame[3][7]. Cuttings of ripe wood of the current season's growth, 15 - 30cm long in a cold frame[8]. Root cuttings in late winter[7]. Division of suckers in the dormant season[7].
Cultivation
Prefers a light warm open loamy humus-rich soil and a position sheltered from north and east winds[2][7]. Prefers a well-drained soil and full sun[7]. Thrives in sun or shade according to another report. Tolerates urban pollution and poor soils[7]. Plants are hardy to at least -15°c if they are sheltered from cold winds[7]. Cultivated as a medicinal and culinary plant in Japan[11], there are some named varieties selected for their ornamental value[7].
