Feijoa
It is a warm-temperate to subtropical plant that will also grow in the tropics but requires some winter chilling to fruit. In the northern hemisphere it has been cultivated as far north as western Scotland but does not fruit every year, as winter temperatures below about -11 °C will kill the flower buds. A lot of feijoa are grown in New Zealand, where the fruit is a popular garden tree and the fruit is commonly available in season.
