Although no specific mention has been seen for this species, the leaves and stems of some, if not all, members of this genus are poisonous[9, 76]. The fruit of many species (although no records have been seen for this species) has been known to cause stomach upsets to some people. Any toxin the fruit might contain is liable to be of very low toxicity and is destroyed when the fruit is cooked[65, 76].
Range
E. Asia - China, Japan.
Habitat
Thickets and woods in hills and at low elevations in mountains, C. and S. Japan[58].

Physical Characteristics
Perennial growing to 1.5m.
It is hardy to zone 8. The flowers are hermaphrodite (have both male and female organs) and are pollinated by Insects.
The plant prefers light (sandy), medium (loamy) and heavy (clay) soils and can grow in heavy clay soil.
The plant prefers acid, neutral and basic (alkaline) soils.
It can grow in semi-shade (light woodland) or no shade.
It requires moist soil.
The plant can tolerates strong winds but not maritime exposure.
It can tolerate atmospheric pollution.
Fruit - cooked. It is usually preserved, used in confectionery or as a tea[183]. The fruit is about 4mm in diameter and is borne in large clusters[200]. Some caution is advised, see notes on toxicity above.
Stems and leaves - cooked[183]. Some caution is advised, see the notes on toxicity above.
Root - cooked. Use with caution, see the notes above on toxicity.
Medicinal Uses
Plants For A Future can not take any responsibility for any adverse effects from the use of plants.
Always seek advice from a professional before using a plant medicinally.
The plant is used to make a skin wash to rid the body of parasites[178]. (The part of the plant that is used is not detailed, it is likely to be the leaves or dried flower stalks.)
Cultivation details
Tolerates most soils, including chalk[200], but prefers a moist loamy soil[11, 200]. Grows well in heavy clay soils. Tolerates some shade but is best in a sunny position[1]. Tolerates atmospheric pollution and coastal situations[200].
There is some confusion over the correct name of this species. It is said to be a synonym of S. javanica by some botanists, but this probably refers to a herbaceous plant, the correct name of which should be S. chinensis. The true S. javanica is a shrub[K].
Propagation
Seed - best sown as soon as it is ripe in the autumn in a cold frame, when it should germinate in early spring. Stored seed can be sown in the spring in a cold frame but will probably germinate better if it is given 2 months warm followed by 2 months cold stratification first[78, 98, 113]. Prick out the seedlings into individual pots when they are large enough to handle. If good growth is made, the young plants can be placed in their permanent positions during the early summer. Otherwise, either put them in a sheltered nursery bed, or keep them in their pots in a sheltered position and plant them out in spring of the following year.
