16 is extreme but it does happen here every so many winters.
We are growing 5-6 different cultivars of mango, 2 types of sapotes, fejioa, starfruit, barbados cherry, passionfruit, guava, allspice, cinnamon, pineapple, banana, cherimoya, 6 types of loquat, etc.
We also grow all the typical stone and pomme fruits too. I estimate we see around 800 chill hours here. We are in a severe cold spot on the outskirts of the city. In town they are lucky to see 350 chill hours.
