PlantFiles: Footstool Palm, Roundleaf Fan Palm, Serdang
Livistona rotundifolia

this palm can survive but not thrive zone 11 areas of CA, as well as Palm Springs. Its a trade off of the hot summers, and the warmer winter nights.

This is a tropical Livistona- one of the few species we can't grow here in Southern California, though heaven knows folks try over and over again. It is one of the fastest growing palms in the world and an extremely uselful and tolerant landscape palm in the tropics. A seedling can turn into a 6-8' trunking specimen palm in only 3 years if given fertilizer and sufficient water. It is also quite tolerant of being dug up and moved. The trunk of this palm is smooth and has an attractive brown, ringed look. The leaves are very large and not that deeply split. It is a beautiful palm. However after visiting the tropics a number of times, it can get a bit old as it is planted nearly everywhere.

And just FYI, there is no zone 11 in California... if there was, you probably could grow this there... there must be Camelot or Atlantis, though.
