A Frond-ly Discussion About Saw Palmetto

Naturally Florida

Saw palmetto (Serenoa repens) is an iconic plant of Florida, often dominating the understory of pine flatwoods habitats. Not only is saw palmetto endemic to Florida and the southeastern U.S., but it has also been referred to as a keystone species! A plant as a keystone species? YES!

Keystone Species - a species on which other species in an ecosystem largely depend, such that if it were removed the ecosystem would change drastically.

For most of the year, saw palmetto fronds stand proud and upright showcasing their unique fan-shaped leaves with long, stiff, pointed leaflets and spikey leaf stems. They reflect the sun’s rays with their waxy coated, muted green and sometimes yellow leaves. From far away, saw palmetto may seem to serve little benefit to the environment other than taking up a lot of space. Upon closer inspection, saw palmetto create their own little world for numerous wildlife species big and small.
