The classification of the genus Actinidia is difficult and the taxonomy of some taxa is still confusing. Various studies since 1984 have estimated the genus to comprise anywhere between 54 - 76 species. The species of Actinidia are highly variable in their vegetative structures, as well as in their flowers and fruits, which is the main reason for the difficulty in the classification of the genus. A detailed study of the genus, based on a wide range of specimens, is needed to clarify the situation and it could be many more years of work until a natural classification system is found - Xinwei LI, Jianqiang LI, Djaja Djendoel SOEJART; Advances in the study of the systematics of Actinidia Lindley; Front. Biol. China 2009, 4(1): pp 55 - 61.
The treatment followed here is based mainly on the Flora of China[], with some later amendments[].

General Information

Actinidia latifolia is a vigorous, deciduous climbing shrub, producing one or more branching stems that scramble over the ground and twine around the branches of other plants for support. The stems can be up to 20 metres long, but more commonly 5 - 9 metres[, ].
The plant is harvested from the wild for local use as a food.

Known Hazards

Climbing into trees on mountain slopes, valleys, thickets and forests at elevations of 400 - 1,700 metres in China[]. Rather rare in hill forests at elevations from 900 - 1,500 metres in Malaysia[].

Cultivation Details

A plant of the warm temperate to subtropical zones, entering into the tropics at elevations over 1,000 metres[]. Although the dormant plant can tolerate some frost, the young spring growth is very susceptible to frost damage[].
Plants in this genus generally prefer a sound loamy neutral soil[, ]. They succeed in semi-shade but full sun is best for fruit production[]. They prefer a sheltered position[].
Fruits are formed on second year wood and also on fruit spurs on older wood[], any pruning is best carried out when the plant is leafless[].
Plants in this genus are notably resistant to honey fungus[].
Dioecious. Both male and female forms must be grown if fruit and seed are required.

Edible Uses

Fruit - raw or cooked. A fairly large fruit, it is 3 - 4cm long and 2 - 3cm wide[]. The fully ripe fruit is brown and hairless[]. It contains a number of small seeds, but these are easily eaten with the fruit[].

Medicinal

None known

Other Uses

None known

Propagation

Seed - best sown as soon as it is ripe in a nursery seedbed. Stored seed, or the seed of plants from colder latitudes, will probably germinate better if it is given 3 months cold stratification[]. Fresh seed germinates in 2 - 3 months at 10°c, stored seed can take longer[]. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in light shade. When the plants are 30cm or more tall, plant them out into their permanent positions[]. Most seedlings are male[]. The seedlings are subject to damping off, they must be kept well ventilated[].
Cuttings of softwood in a frame[].
Cuttings of half-ripe wood in a frame. Very high percentage[].
