Gardeners' Notes:

I purchased mine as Coccothrinax readii- if this is indeed the same palm then I must mention the fragrance of the flower! It is not fragrant for long- maybe for the initial 12 hours arter the inflourescence opens. But if you can be there at the right moment it is a stunning smell- soft and sweet and just heavenly.
This is a most attractive palm- especially when smaller. A good easy grower for me and not a problem ever.

This is one of the two most common Coccothrinax in cultivation in the US- has silvery undersides to the leaves (as do about 3-4 other species so careful on the identification). This palm has a slender trunk with retained leaf bases and a thatch of thick fiber (very ornamenal). The crown is sparse, usually consisting of 5-8 fan leaves on thin, drooping petioles. It is a dainty looking palm and makes a great palm for smaller yards. It likes water. Slow grower in southern California- much better suited to a humid warm climate like that in Florida. Native to south Florida and the Bahamas.
