California Fan Palm Tree Profile
Scientific name: Washingtonia filifera
Common names: California Fan Palm Tree is also known as Desert Fan Palm, American Cotton palm, Arizona Fan Palm.
Origin: It is native to North America.
Appearance: The California Fan Palm has heavy grey trunk ringed with old leaf scars. When the leaves die they bend downwards and form a skirt around the trunk. Trunk is a little swollen at the base and can get up to 3ft in diameter at its widest point. Palmate, or fan shaped, leaves emerge from the trunk forming a loose and open crown. Leaves are grey-green, about 4-6ft across with tips of fronds arching down. The leaf stems of mature palms have curved thorns. The leaflet edges have fibrous white cotton-like threads.
Flowers/Fruits: In the early summer, the California Fan Palm produces creamy flowers that hang in clusters from the crown. Flowers are small held by stalks that extend beyond foliage. The California Fan Palm has male and female flowers on the same inflorescent. The flowers are followed by black fleshy berry-like fruit, ½ inch in diameter with a single seed inside that mature sometime in September.
Growth Rate: Moderate. In the wild Washingtonia filifera is known to grow up to 70ft tall but in cultivation it is usually not more than 30-40 ft tall and 5-10 ft wide.
Outdoor/Indoor Use: Both. California Fan Palm Tree can also grow in a pot.
Cold Tolerance: It is cold hardy to about 15-20 F and can tolerate frost. It also recovers pretty quickly from the damage. Great for USDA Zones 8b (15 to 20 F) to 11 (above 40 F).
There is a great book, written by David A. Francko that I really like, it’s called “Palms Won’t Grow Here and Other Myths: Warm-Climate Plants for Cooler Areas”. It goes into the details on how you can grow cold hardy palms in zones 7, 6 and even 5. This is the perfect foundation book for the gardener who would like to see a banana next to his cherry tree and a palm between his maples. It got great reviews and 5 out of 5 stars rating on Amazon.
Light Req: Partial shade to full sun. It likes full sun but can also grow in partial shade.
Water Req: Moderate. It can also tolerate drought but does best in moist well drained soil. It can tolerate alkaline soil.
Maintenance: Easy. To prevent nutritional deficiency, apply good quality palm fertilizer that has continuous release formula twice a year during growing season.
Insects and Diseases: This pest and disease resistant palm is very easy to maintain.
Propagation: Propagated by seed.
