Saw palmetto

Serenoa repens, commonly known as saw palmetto, is the sole species in the genus Serenoa. It is a small, shrubby palm native to the southeastern United States, most commonly found in Florida and along the Atlantic and Gulf Coastal plains. This plant is characterized by its fan-shaped leaves with sharp, sawtooth-like spines along the petioles, which gives the plant its common name. The plant typically grows in clumps and can form dense thickets, spreading through underground rhizomes.
