Another fairly cold hardy citrus is the Mexican lime or Key Lime as it is also known. It is not as cold hardy as the Satsuma orange but will stand temperatures down to 30 F.

If you want to grow a Key Lime outside you should build a protective enclosure for the winter and place a light bulb inside. You can use an automatic freeze protection thermostat to turn the light bulb on when the temperature gets to near freezing.
