Except that wouldn't matter. Anyone who's an avid love of citrus fruit would know that citrus requires cold weather to set. Thus your original reply of the best citrus growing during the winter months would be correct, regardless of where it came from. As South America is in the southern equator, it was winter there when it was summer here. Likewise, during your summer you receive citrus grown in countries from the southern equator during their winter.
The majority of orange varities in motion are universal. I can buy seville and jaffa oranges here. Species not native to the Americas.

Every time you remind me of this, I grow even more jealous. They're due to come into season soon. I'll snap a photo and post it in the espresso thread. You will find yourself laughing and feeling sorry for us in the US for the "blood" oranges we grow and import.
