NOTE: The majority of palm trees around the world live in Zones 10a through 11. Thus, most people associate palm trees with a feeling of the tropics, the jungle, or the rainforest. Whereas, hardwood trees and “leafy” trees are known to grow in colder climates such as seasonal ones (lose their leaves in Fall, etc.). All palm trees are evergreen, meaning they don’t drop their leaves every year. However, some palms can be grown in cooler climates than they’re used to. In these climates, they may lose their healthy leaves (defoliate) and then push new growth out of the center when the weather warms up. However, if too much damage is done by the cold, the palm may not grow back.
