Typically 3-8 (15) ft tall by 4-6 (10) ft wide

Esperanza de vida:

Long-lived perennial

Color de la flor:

white

Color de la fruta:

black

Fenología:

Evergreen. Blooms spring and summer. Slow growing. Individual stems may be over 100 yrs. Clone forming. Clones may be thousands of years old.

Destacado por:

Showy Flowers, Hurricane Wind Resistance, Thorns, Interesting Foliage

Paisajismo

Usos recomendados:

Adaptive to many landscape uses: specimen plant, mass plantings, naturalistic settings.

Consideraciones:

Be sure to plan for enough room for this spreading plant.

Disponibilidad:

Native Nurseries, FNPS Plant Sales, Seed

Propagación:

Seed and fragments of rhisomes. Most nursery stock is established from rhisomes as seeds are slow to sprout and initial growth is slow.  Once established, rate of growth depends on variety (silver & green), soil and management.  Silver saw palmettos can have rapid growth while green palmettos grown in low nutriet, dry sands can be very slow growing.

Luz:

Full Sun, Part Sun

Tolerancia a la humedad:

Siempre inundado---------------------------------Extremadamente seco

Ecología

Fauna:

Pollinators, Butterflies, Caterpillars, Birds, Mammals

Larval host plant for monk skipper ( Asbolis capucinus ) and palmetto skipper ( Euphyes arpa ) butterflies.





Nectar plant for Bartram's scrub-hairstreak (S trymon acis ), atala ( Eumaes atala) and other butterflies.





Documented bees visiting the plant include Colletes banksi, C. brimleyi, C. mandibularis, C. rzudus, Colletes sp. A, Hylaeus graenicheri, Agaposternon splendens, Augochlora pura, Augochlorella aurata, Augochloropsis metallica, A. sumptuosa, Dialictus miniatulus, D. nymphalis, D. placidensis, D. tegularis, Evylaeus pectoralis, Halictus ligatus, Sphecodes heraclei, Coelioxys sayi, Dianthidium. floridiense, Megachile policaris, M. xylocopoides, Epeolus erigeronis, E. glabratus, E. zonatus, Apis mellifera, Bombus impatiens, B. pennsylvanicus , and Xylocopa virginica krombeini (Deyrup et al. 2002).  Another study documented 311 species of flower visitors including 121 species of bees, 117 species of flies, and 52 species of beetles (Deyrup and Deyrup 2012).





Saw palmetto also attracts Syrphid flies including the flower fly,  Meromacrus acutus , which apparently is a saw palmetto specialist (John Lampkin, 2019)

Palmetto berries are important bear food.





More than 100 bird species, 27 mammals, 25 amphibians, 61 reptiles, and countless insects use it as food and/or cover (Maehr and Layne 1996).





As Maehr and Layne summarize, “ If saw palmetto is not the plant species most highly used by Florida wildlife, it certainly is in close contention for that honor.”

Hábitats nativos:

Mesic flatwoods, wet flatwoods, dry flatwoods, scrubby flatwoods, scrub, hardwood hammock. Generally absent from cleared sites even after abandonment.

Etnobotánica:

The fan-shaped leaves have been widely used for thatch roofing and have been used for baskets and mats.

Comentarios generales:

There are two color morphs: green and silver. Silver is associated with the east coast, but may occur anywhere within the range.  It is typically larger and faster growing than the green morph.



Saw palmetto is exceedingly important to the fire ecology of Florida. Keeping saw palmetto dominated woodlands burned is essential both for ecology and safety. Overgrown saw palmetto thickets are severe fire hazards associated with catastrophic firestorms during dry windy weather. Tall palmetto understories can carry fires into the overstory and kill mature trees (Sackett 1975; Hough and Albini 1978. exerpted from Duever, 2011).



Saw palmetto is frequently clonal.  A clone is a group of plants that are genetically identical as it is formed by the spreading of underground stems which produce new visible genetic "twins" called ramets.   For saw palmetto, the group of  individuals that make of the clone may continue to spread for thousands of years, though the underground connections break with time.  Clones can become quite large, and it takes genetic studies to definitively map an idividual clone.  One such study found that in a 20x20m (approximately 66x66ft) study plot, based on modeled rates of spread, the oldest of their clones was likely over 5,500 years old.  The researchers concluded that other clones (not studied) might exceed 10,000 years in age.  Individual plants  do not live to such ripe old ages, and individual plants can grow fairly quickly (Takahashi, et al. 2011).
