Where are Chinese gooseberries from?

Mostly New Zealand. Also called Kiwi fruits.

originally China. they came to NZ with the gold miners and it would seem almost became extinct in China. After they were renamed Kiwi Fruit for commercial reasons NZ sent live plants back to China for re establishment in the country of origin.

Despite the name, kiwifruit are not native to New Zealand. Seeds were brought to New Zealand in 1904 by Mary Isabel Fraser, the principal of Wanganui Girls' College, who had been visiting mission schools in China. People thought the fruit had a gooseberry flavour and began to call it the Chinese gooseberry. New Zealand began exporting the fruit to the US in the 1950s. This was the height of the Cold War and the term Chinese gooseberry was a marketing nightmare leading to the name kiwifruit.
