Key Lime and Meyer Lemon, grown north of Birmingham, Alabama.
Our latitude here may be more or less the same as northern Morocco and Libya, but it still gets nice and cold. The hardiest citrus plants would still survive outside during the winter, but the problem is that the fruit would not. Who wants that? The answer is growing in pots, aka containers.
The advice here is simple: buy the largest size container you can handle, and then get a plant trolley/buggy to wheel them around with. I made my own out of pressure treated pine. We wheel our plants in in November and put them outside in April. The honeybees love the blooms, and can locate them within minutes of putting the plants outside. It’s almost scary.
Our favorite varieties are the Key Lime pictured, Satsuma Mandarin Oranges, and Meyer Lemon. Year in and out the Meyer is the best, though it is really a hybrid between lemons and oranges. Even in a container it has enormous fruit.
You can also underplant your citrus with something like Christmas Cactus, to make it more decorative.
