I bought a Hamlin orange tree from Lowe's. I did some research on it, and it's supposed to be a great orange tree for South Florida, as it has a smaller to medium sized orange, but it's very sweet, which is great for me! (I'm a fruit freak).
Here's a picture of my tree, it's blossoming and fruiting. I had a bee on a blossom but couldn't manage to take a picture quick enough.
