As a homeowner or gardener, you're likely looking for plants that can thrive in a variety of conditions, including cold temperatures. While many palm species are sensitive to frost, there are several cold hardy palms that can tolerate temperatures as low as 20°F (-7°C) and even survive brief periods of snow. In this article, we'll explore the best cold hardy palms for pots and provide tips on how to grow them in your outdoor space.
Choosing the Right Cold Hardy Palm for Pots
