Eleutherococcus divaricatus is a spiny, deciduous shrub of thin, open habit; it can grow up to 3.5 metres tall[
The plant is harvested from the wild for local use as a food.
E. Asia - Japan, Korea
A rather rare plant, growing in the mountains all over Japan[
Eleutherococcus divaricatus is a moderately cold-hardy plant, being able to tolerate temperatures down to around -20°c when fully dormant. Plants are hardy to at least -10 to -15°c if they are sheltered from cold winds[
Species in this genus are usually easy to grow and tolerant of a wide range of soils and conditions. They generally grow best in a well-drained, open loamy soil, succeeding in full sun to moderate shade[
]. They tolerate poor soils and atmospheric pollution[
The plant is early to lose its leaves in autumn[
A spineless form, Eleutherococcus divaricatus inermis (Nakai) H. Ohashi, has been reported[
Leaves - cooked[
]. They are parboiled, then dried and used as a winter vegetable[
The leaves are used as a condiment[
The dried leaves are a tea substitute[
Seed - best sown as soon as it is ripe in the autumn in a cold frame[
]. It can be slow to germinate. Stored seed requires 6 months warm followed by 3 months cold stratification[
] and can be very slow to germinate[
]. 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.
