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

Succeeds in an open loamy soil[1], preferring a well-drained humus-rich soil in full sun[7]. Tolerates poor soils and atmospheric pollution[7]. Plants are hardy to at least -10 to -15°c if they are sheltered from cold winds[7]. A spineless form, Eleutherococcus divaricatus inermis (Nakai) H. Ohashi, has been reported[9].
