Other Common Names: Desert Fan Palm, and Petticoat Palm
Related Species: Thread Palm, Mexican Fan Palm (Washingtonia robusta).
Origin: California fan palms occur near streams and springs on borders of the Colorado Desert of California and southwest Arizona. The related W. robusta is native to arid regions of Sonora and Baja California, Mexico.
Adaptation: The palms are extensively grown in many parts of California and are common along the Gulf Coast and in Florida, as well as in other parts of the world, particularly those with Mediterranean-type climates. They are hardy to 18 degrees F (USDA Zones 8-11).
DESCRIPTION
Growth Habits: The robust palms grow at a moderate rate to about 50 feet with a large canopy of several dozen leaves. The cylindrical, closely ringed and fissured trunks are swollen at the base and covered with a "petticoat" of dead, pendant leaf stalks, extending almost to the ground. The trees are especially valuable as avenue plants, and are widely used as such in southern California and Arizona. The also make handsome specimens They are not a particularly good choice for container culture because of their relatively fast rate of growth.
Foliage: The immense, fan-shaped, costapalmate, grayish-green leaves are 3-4 feet long and 6-7 feet wide, dividing about halfway into 50-70 pointed segments that bend and split at the tips with threads in between. The leaves are edged with prickles and stand well apart in an open crown.
Flowers: Numerous white to apricot, bisexual flowers are borne on 9-15 foot arching, branched inflorescences that hang down from among the leaves. Pollination is by wind and various insects.
Fruit: The berry-like, small fruits are brownish-black and have a thin, sweet pulp that tastes somewhat like dates or butterscotch. Each fruit contains a single seed.
