Physical Characteristics

An evergreen tree growing to 15m at a slow rate. It is hardy to zone 8. It is in leaf all year, and the seeds ripen from October to November. The flowers are dioecious (individual flowers are either male or female, but only one sex is to be found on any one plant so both male and female plants must be grown if seed is required) and are pollinated by Wind. The plant not is self-fertile. We rate it 3/5 for edibility and 0/5 for medicinal use.

The plant prefers light (sandy), medium (loamy) and heavy (clay) soils. The plant prefers acid, neutral and basic (alkaline) soils. It can grow in full shade (deep woodland) semi-shade (light woodland) or no shade. It requires moist soil.

Cultivation details

Succeeds in ordinary garden soil, tolerating some lime[1]. Requires a sheltered position and either high humidity or a moist riverside soil[200]. Dislikes wind exposure[200]. Tolerates woodland shade very well[200]. Requires hot, very humid summers for best growth[200].
A vulnerable species in the wild, where it is at risk of becoming extinct[266].
This species is not hardy in all parts of Britain, but trees can be grown outdoors in the milder parts of the country[81].
The seed takes two summers to mature[229].
There is some confusion over the correct name of this species, with some authorities seeing it as no more than a sub-species of T. fargesii[266].
Plants are dioecious, but sometimes monoecious with dioecious branches. Male and female plants must usually be grown if seed is required.

Propagation

Seed - best sown as soon as it is ripe in a cold frame. Some of the seed should germinate in the following spring though much of it might take another 12 months. Stored seed requires a period of cold stratification and can take 18 months or more to germinate. Prick out the seedlings into individual pots as soon as growth is observed and grow them on in light shade in the greenhouse for at least the next couple of winters, making sure to pot them on into larger pots as and when required. Plant them out into their permanent positions in early summer when the plants are at least 20cm tall.
Cuttings of half-ripe shoots in late summer[1]. Cuttings do not grow well[11].
Layering.
