This is the only palm that is native to California. It also appears in other parts of the Western US. It is found clustering in spring-fed oases in desert areas. The palm grows to a height of 50 feet with a trunk diameter of 2 feet. The evergreen fan-shaped leaves can extend 15 feet in diameter. The palm fronds have fibrous threads at leaf segments. Spent leaves do not drop naturally. They form a light brown skirt below the green fronds. California fan palms produce edible fruit (not dates) which grows in clusters.
