Serenoa repens Saw Palmetto1

Edward F. Gilman2


Saw palmetto is an extremely sturdy palm with great textural interest that blends in well with natural or seaside landscapes (Fig. 1). This low, clumping, bushy palm has large, fan-shaped leaves and multiple trunks that creep along the ground, creating a dense ground cover. Most saw palmettos have green leaves, but a form with blue leaves can be found along the southeast coast of Florida. Three-foot-long flower stalks appear in spring, covered with small, yellow-white, fragrant flowers, the source of a commercial high-grade honey. The flowers are followed by small, yellow berries that turn black, ripening August through October. These berries are an important food source for many mammals and birds.

Use and Management

Surviving only on rainfall once established, saw palmetto grows on any well-drained soil in full sun to shade, and is highly salt tolerant. Best transplanted when young, larger specimens ideally should not be removed during land clearing, since plants grow very slowly and transplant so poorly. This happens because stems frequently grow along the ground as they droop under the weight of the foliage. Therefore, the root system may not be located beneath the foliage but could be 5 to 10 feet away at the base of the stem. Twice the desired number of collected saw palmetto are often planted since mortality is high. Saw palmetto is becoming more available in containers from nurseries. Homeowners should make an effort to leave native stands in place beneath existing trees when developing a new lot since they require no maintenance.
Saw palmetto should be planted on 3- to 5-foot centers to establish a new mass planting. They make a wonderful ground cover effect beneath existing or newly planted trees. Upright plants can be grown into beautiful multi-stemmed specimens but these are not common and quite expensive.
The variety sericea, silver palmetto, is recognized by some authorities and has beautiful silver leaves.
Propagation is usually by seed but seedlings grow very slowly.
