Cultivation
Requires a light lime-free soil in sun or semi-shade. If planted out when young into a planting hole that has been filled with a light lime-free soil the plants will successfully grow into the surrounding soil. Prefers a warm sheltered position with protection from the morning sun. Dormant plants are hardy to about -15°c but the young growth is liable to be damaged by late frosts. A very ornamental plant but it is slow to establish itself and is slow growing. There are some named varieties. The sub-species S. japonica fargesii is stronger growing in Britain. The flowers have an exquisite scent. Plants in this genus are notably resistant to honey fungus.
Propagation
Seed - requires stratification and is best sown in a cold frame as soon as it is ripe. Stored seed requires 3 months warm then 3 months cold stratification. Germination is usually good, prick out the seedlings into individual pots once they are large enough to handle. Overwinter in a greenhouse for the first winter and plant out in late spring. Cuttings of half-ripe wood, July/August in a frame. Layering in autumn.
Other Uses
Beads Oil Wood. The fruits are used as beads in rosaries etc. An oil is obtained from the seed. No further details are given. Wood - fine-grained. Used to make umbrella handles.
