Depending on the severity of your winters, there are many palm plants that grow well outdoors, including the Dwarf Palmetto Palm Tree, Dwarf Palmetto Palm Tree, Pindo Palm Tree and Windmill Palm Tree. Most palm plants can survive winters with temperatures as low as 20 degrees Fahrenheit with a cover.
There are even more options for warmer climates, including date palms and the Sylvester Palm Trees. Palm plants and trees typically prefer sunny, dry climates without excessive humidity. To protect outdoor palms in winter, you can purchase or make a cover to keep them from freezing. Palm plants tend to be slower growing, especially without full sunlight.
