Actinidia rubricaulis
Family: Actinidiaceae
What it is like
Actinidia rubricaulis is a deciduous Climber growing to 10 m (32ft 10in). It is frost tender. It is in flower from May to June, and the seeds ripen from October to November. The species is 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 is pollinated by Bees, insects. The plant is not self-fertile. Suitable for: light (sandy), medium (loamy) and heavy (clay) soils. Suitable pH: mildly acid, neutral and basic (mildly alkaline) soils. It can grow in semi-shade (light woodland) or no shade. It prefers moist soil.
Height (m): 10

How it is grown
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. Closely related to A. coriacea, it is part of the A. callosa group but with smaller fruits. Cultivated for its edible fruit in China. Plants in this genus are notably resistant to honey fungus. Dioecious. Male and female plants must be grown if seed is required.
Propagating it: Seed - sow spring in a greenhouse. It is probably best if the seed is given 3 months stratification, either sow it in a cold frame as soon as it is ripe in November or as soon as it is received. 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 in the greenhouse for at least their first winter. When the plants are 30cm or more tall, plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Most seedlings are male. The seedlings are subject to damping off, they must be kept well ventilated. Cuttings of softwood as soon as ready in spring in a frame. Cuttings of half-ripe wood, July/August in a frame. Very high percentage. Cuttings of ripe wood, October/November in a frame.
