Asia, Australia, China, Japan, Korea, Tasmania,
Cultivation
An easily grown plant, it succeeds in most soils, but is in general more productive of seeds when grown on soils of moderate fertility. It does less well in rich heavy soils or poor ones. Does well in a loamy soil. Very suitable for an alkaline soil, but it dislikes very acid soils. Plants are fairly wind tolerant. Members of this genus bear transplanting well and can be easily moved even when relatively large.
Propagation
Sow seed as soon as it is harvested in autumn in a cold frame; it germinates in late winter or spring. Stored seed should be pre-soaked in warm water for 48 hours, then given 2 weeks of warm stratification followed by 3–4 months of cold stratification. Germination takes 1–6 months at 20°C. Prick seedlings into individual pots when large enough to handle and grow on in a cold frame or sheltered spot through their first winter. Plant out into permanent positions in late spring or early summer. Layering in autumn is easy and takes about 6 months. Suckers can be divided in early spring and planted straight into permanent positions.
Other Uses
An oil is obtained from the seed.
