Kiwi fruit, Chinese gooseberry.

I'm thinking about trying to grow these outdoors.
I'm just wondering if anyone is having any real success.
Would be interested to know if they ripen ok in the UK outside.
Only the ones I'm buying in the supermarkets are pretty sour and not ripe and as is usual with fruit it's much better if it ripens on the plant.

 

Just reading and it would seem they can be grown successfully in the uk. You need both male and female plants. One male can pollinate up to 8 females so a happy plant for sure. They may take 4 years to reach maturity. Not sure about the winter would they be frost hardy.

 

I think they probably are frost hardy enough, my main concern is if the fruits will ripen in a normal British summer
