Palm trees have become an unofficial symbol of Southern California and they’re abundant in San Diego. They’re seen lining beaches, highways, swaying in the wind on city streets, and in just about every shopping center parking lot. Their image conjures up feelings of leisure, relaxation, and living the good life. Unlike the palm trees, you’d find in the southern United States or Hawaii, the California palm tree has a distinct shape. These tall and skinny trees grow up to 75 feet tall and have leaves shaped like a fan that fold like an accordion. The leaves themselves can reach about 6 feet long and wide.
