The Mediterranean fan palm trees form clumps than can grow up to 15' in height. The triangular, fan-shaped leaves grow to about 20-24" long by 24" wide. They are deeply divided into multiple segments that are themselves split at the tip and they are supported on 3-4' stems. Cold hardy California Fan palm trees are an extremely variable plant both in color (the leaves range from blue-green to gray-green to yellow-green) and in shape. Some plants form suckers more freely than others to become very shrubby plants that may reach 15' in width. Other individuals can be seen that are almost dwarf growing just 5' tall by 4' wide. These days it is popular to remove all but a few of the suckers and to prune the leaves to form a cluster of clear-trunked "mini" palms.
