Growth—

A plant ofwarm temperate to subtropical areas in China, where it is found at elevations of 1,200 - 2,300 metres. It is likely to succeed outdoors at least in the warmer areas of the temperate zone. The mature growth can tolerate at least some frost, though young growth in the spring is very susceptible to frost damage[1]. Prefers a sound loamy neutral soil[2, 3]. Succeeds in semi-shade but full sun is best for fruit production[3]. Prefers a sheltered position[3]. Young spring growth is susceptible to frost damage[1]. Fruits are formed on second year wood and also on fruit spurs on older wood[4], any pruning is best carried out in the winter[5]. Plants in this genus are notably resistant to honey fungus[3]. A dioecious species - both male and female forms must be grown if fruit and seed are required. Female plants produce morphologically perfect flowers with well-developed pistils and stamens, but their stamens produce nonviable pollen; flowers of male plants have small, rudimentary ovaries without viable ovules but their stamens release viable pollen[6].

Propagation

Seed - sow spring in a greenhouse[7]. It is probably best if the seed is given 3 months stratification[8], either sow it in a cold frame as soon as it is ripe in late autumn or as soon as it is received. Fresh seed germinates in 2 - 3 months at 10°c, stored seed can take longer[7]. 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[PFAF]. Most seedlings are male[4]. The seedlings are subject to damping off, they must be kept well ventilated[8]. Cuttings of softwood as soon as ready in spring in a frame[PFAF]. Cuttings of half-ripe wood, mid summer in a frame. Very high percentage[8]. Cuttings of ripe wood, autumn in a frame. Cite as: Temperate Plants Database, Ken Fern. temperate.theferns.info. 2026-02-20. <temperate.theferns.info/plant/Actinidia+rudis>
