California Fan Palm
Washingtonia filifera
Climate Resiliency
3 out of 5 stars
Not suggested for small landscape spaces, very large palm. Same fan-shaped leaves as W. robusta (Mexican Fan Palm), but with a thicker trunk. If desired, remove fronds only after they have turned brown. Remove flower stalks before seeds set to prevent reseeding in the landscape. May be susceptible to Budrot (Penicillium vermoeseni) fungus. Spay bordeauz as a preventative to control. Subject to lighting injury.
