Summary
Source: WikipediaActinidia rubus is a woody climbing vine of the Actinidiaceae family and native to mountainous areas of the Chinese provinces of Sichuan and Yunnan. Its branchlets and petioles are deep reddish brown, and its yellow dioecious flowers develop in June and are pollinated by bees and insects.
Description
A climbing shrub. It loses its leaves during the year. The branches have reddish-brown hairs. The leaves are pale green underneath. The leaves are broadly oval and 8-9 cm long by 6-7 cm wide.
Edible Uses
The fruit can be eaten raw or cooked. It contains several small seeds, though these are soft enough to eat along with the rest of the fruit.
Traditional Uses

Where It Grows
Asia, China,
Cultivation
We have very little information on this species and do not know if it will be hardy in Britain, though judging by its native range it could succeed outdoors at least in the milder areas of the country. It is closely related to A. holotricha. The following notes are based on the general needs of the genus. Prefers a sound loamy neutral soil. Succeeds in semi-shade but full sun is best for fruit production. Prefers a sheltered position. Young spring growth is susceptible to frost damage. Fruits are formed on second year wood and also on fruit spurs on older wood, any pruning is best carried out in the winter. This is a climbing plant, supporting itself by twining around branches etc. Plants in this genus are notably resistant to honey fungus. Dioecious. Male and female plants must be grown if seed is required.
Propagation
Sow seed in spring in a greenhouse, ideally after 3 months of stratification. Alternatively, sow fresh seed in a cold frame as soon as it is ripe in November or upon receipt. Fresh seed germinates in 2–3 months at 10°c; stored seed may take longer. Once seedlings are large enough to handle, prick them out into individual pots and grow on in light shade in the greenhouse for at least their first winter. Plant out into permanent positions in late spring or early summer, after the last expected frosts, once plants are 30cm or more tall. Note that most seedlings are male. Seedlings are prone to damping off and must be kept well ventilated. Softwood cuttings can be taken as soon as growth is ready in spring in a frame. Half-ripe cuttings can be taken in July/August in a frame, with a very high success rate. Ripe wood cuttings can be taken in October/November in a frame.
Other Uses
None known
Notes
There are 40-60 Actinidia species. The Actinidiaceae are a mainly tropical family.
