I just watched a rerun of a QI show - hoaxes. Where did the elves get the idea oranges do not turn orange if left on the tree long enough? They do in Australia.

I've seen lots of orange oranges on trees, all over the place.

I think the idea was that in South-America they're likely to be picked as green and sold as such for the local market, but Europeans are used to them being orange, and that they don't have to become orange to be ripe.

I think they were also pointing out that there are species of oranges which are green when ripe and won't turn orange no matter how long you leave them on the tree.

This is clearly not the case for all oranges but, just because you see an orange that's green, it doesn't necessarily mean it's unripe.

I know what those ones are called:
Apples
or
Greens.

also from QI, the primary flavour molecules of oranges and lemons are chiral mirror images of each other (enantiomers)

Meanwhile, Aussie oranges go '70s retro.
