Smilax sieboldii is a climbing plant with branched, prickly stems that become more or less woody and persist.
The plant is harvested from the wild for local use as a food.
E. Asia - China, Japan, Korea
Forests, thickets and grassy slopes; at elevations from near sea level to 1,800 metres, occasionally to 2,500, metres[
Succeeds in most soils in sun or semi-shade[
A dioecious species - both male and female forms must be grown if fruit and seed are required.
Leaves and young shoots - cooked[
Seed - sow early spring in a warm greenhouse[
]. This note probably refers to the tropical members of the genus, seeds of plants from cooler areas seem to require a period of cold stratification, some species taking 2 or more years to germinate[
]. We sow the seed of temperate species in a cold frame as soon as we receive it, and would sow the seed as soon as it is ripe if we could obtain it then[
]. When the seedlings eventually germinate, prick them out into individual pots when they are large enough to handle and grow them on in the greenhouse for at least their first year, though we normally grow them on in pots for 2 years. Plant them out into their permanent positions in early summer.
Division in early spring as new growth begins[
]. Larger divisions can be planted out direct into their permanent positions. We have found it best to pot up the smaller divisions and grow them on in a lightly shaded position in a cold frame, planting them out once they are well established in the summer.
