Saw Palmetto (Serenoa repens) – A small fan palm that grows up to 6’. The fruit is a large reddish-black drupe (a fleshy fruit with thin skin and a seed). Cherries, almonds and dates are examples of drupes. The plant is used as food by the insect order Lepidoptera, which includes many species of moths and butterflies. It has a sprawling trunk and grows in clumps or dense thickets in sandy coastal lands or as undergrowth in pine woods or hardwood hammocks. It is hearty, extremely slow growing and long-lived, with some plants in Florida as old as 700 years. While the saw palmetto has been used for many purposes by humans, an entire industry developed around its use in the past few decades; palmetto products have become popular due to their effectiveness in treating prostate problems.
