it would be really hard to ID exactly until it flowers/fruits.

I would guess Valencia or washington naval based on popularity alone. Whatever it is i doubt it will be gross tasting unless it a trifoliate orange but that would be obvious even without fruit.

Brad, glad you've been lurking on the forum. As you probably know, Florida is a restricted state, and no citrus can be taken out of the state due to several serious citrus diseases. So, although your girlfriend was doing something thoughtful, you might want to let her know what she did was actually illegal. It's how HLB and Citrus Canker spreads. I'm shocked that there are citrus being sold at the airport, as the quarantines have been in place in Florida now for several years. If this is an orange, likely it will be sweet as most all oranges are sweet. Impossible to know what kind of orange it is until it produces fruit.

just curious. When did the ban start?

It seems that the ban on moving citrus from Florida started in January, 2008. Here in southern California, when you buy a citrus tree, it has a tag on it that says it may not be moved from the county where it was purchased.

Here is a link that might be useful: citrus restrictions

Thanks for the follow ups. I knew about restrictions moving citrus into FL - never realized there were restrictions on moving them out of Fl. I doubt having a citrus in Chicago is going to do any harm to Chicago citrus trees. In any case, I guess I will just play the waiting game and see what happens. It is nicely coming into its own, and makes a nice tree.

Brad, Your now wife brought this out of FL 5 years ago; you didn't break any laws. Doing so today would be a violation. Those airport kiosks were selling these little trees long after it became illegal to remove citrus from FL, and many people did unknowingly violate the law. How they got away with continuing to sell them, I do not know.
