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[8]. Cuttings do not grow well[9].

Cultivation

Succeeds in ordinary garden soil, tolerating some lime[8]. Requires a sheltered position and either high humidity or a moist riverside soil[10]. Dislikes wind exposure[10]. Tolerates woodland shade very well[10]. Requires hot, very humid summers for best growth[10].

This species is not very hardy in Britain, it only succeeds outdoors in the milder areas of the country[8]. It succeeds outdoors at Kew[9], a tree was 8 metres tall in 1970[11]. The seed takes two summers to mature[12]. The edible seed of this very ornamental evergreen tree is often sold in local markets in China. Closely related to T. nucifera[10].

Plants are dioecious so both male and female plants are required if seed is to be produced. Occasional trees are monoecious with dioecious branches.
