The site is "Explore Seasonal Fruit and Vegetables in Europe". Not "European Union". A map of Europe is shown. And there is no mention of tropical climate. So we must assume they mean metropolitan France and I can assure you that no banana or avocado grows there.
And even if they were talking about the whole territory of France, nowhere on this territory there are Apples being harvested right now.
Legally, most of France's ex-colonies that haven't become independent are just bits of France these days (making it different from, say, the UK, where the rump former colonies usually have special legal status).
They are also part of the EU, which wasn‘t the case in the British colonies when the UK was still part of the EU.
Funny to think that there's a land border between Brazil and the EU.
