This Florida native palm normally grows as a much branched clumping shrub with prostrate stems. Small fan shaped yellow-green leaves are clustered at the ends of the many stems. The leaf stalk (petiole) margins are lined with fine teeth giving the plant its common name. A form with bluish green leaves is an attractive alternative to the more common green form. Occasionally individuals with ascending trunks can reach 10 feet or more in height. Plants are perennial, evergreen and very long lived.
Mature Size: Shrub form clumps rarely exceed six feet tall but may spread for many feet over long periods of time.
Growth Rate: Slow to Moderate
Plant Habit: Spreading/Clumping
Plant Spacing: 3 to 5 feet for faster coverage
Ornamental Characteristics & Uses:
Foliage Color: Yellow-green or bluish green on different individuals

Attracts Wildlife: Flowers are a source of nectar and pollen for bees in spring. Small mammals and birds are known to eat the olive sized fruit in fall and winter.
Uses: This plant is best used in natural areas or landscapes with a native plant theme. The trunked forms are excellent as specimen trees, singly or in groups. It is a very salt tolerant species so is an excellent choice for seaside plantings.
