Jubaea x Syagrus

Home›Palms For California›Jubaea x Syagrus

Pronunciation: jew-BAY-uh x sigh-AHG-russ
Common Name: none

Jubaea chilensis x Syagrus romanzoffiana is slowly becoming a more common palm in California, partly due to its tolerance of so many different conditions, but mostly because growing hybrids is becoming more of a popular thing to do. This cross makes for a fairly impressive, large, fast growing palm. But like most hybrid palms, finding one is often a challenge.
