Kiwi

Hi there ...unless your plant is "Jenny" which can be self-fertile but which is not entirely hardy ...you would need two plants...one female and one male - obviously!! I have had a plant for 20+ years and the season just is not long enough up here - but it is a wonderful sight as it winds its way up my massive eucalyptus tree - so I don't mind not having the flowers or fruit.!!
Anyway - I have just checked with the RHS and they say the following...and I hope it helps....and I guess you will just have to be patient for a few years...LOL

"Although not difficult to grow, kiwi fruit need careful training and pruning to maximise their fruiting potential

Kiwi fruit (Actinidia deliciosa) is a vigorous, twining, deciduous vine capable of growing to 9m (30ft) tall. It is a warm-temperate plant that needs sun and shelter; young shoots are extremely vulnerable to frosts. The large, heart-shaped leaves are ornamental in themselves.

It grows best on a south- or west-facing wall, but can be grown in the open in milder areas on a sturdy support such as a pergola. Plant 3-5m (10-17ft) apart in fertile, well-drained soil rich in organic matter. Regular summer watering and feeding is required.

Pollination
Male and female flowers are produced on separate plants, so both are needed for fruit (borne on one-year-old wood, three to four years after planting). One male can pollinate up to eight females
Training
Kiwi fruit are best trained as espaliers on horizontal wires."

Ours has bloomed last year, but no kiwi's, and this year there are fruits te be seen. Let's hope....;-)
