Pronunciation: suh-BALL//SAY-bull ROW-zee-eye
Common Name: Savannah Palmetto
Sabal rosei is a moderately rare species in California, but it shows up at several botanical gardens, and sometimes in a nursery for sale, too. It is a fairly skinny Sabal with a relatively narrow crown as well, considering it grows fairly tall in California. Probably this is a palm that looks better in groups than by itself.
