Smilax trinervula is a Deciduous Perennial up to 1.00 metres tall.
It has edible uses.
E. Asia - China, Japan.
Mountains, C. Japan[
]. Forests and thickets at elevations of 400 - 1700 metres in Fujian, Guizhou, Hunan, Jiangxi and Zhejiang provinces[
We have very little information on this species and do not know if it will be hardy in Britain, though judging by its native range it should succeed outdoors in many parts of the country. The following notes are based on the general needs of the genus.
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.
Young plants - cooked[
Fruit - raw[
]. The red berries are about 6mm in diameter[
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.
