Serenoa repens
treeSaw palmetto (Serenoa repens) is a slow, clumping, fan-leaved native palm of the Southeastern US, usually 4 to 8 ft tall, forming vast colonies in pine flatwoods, scrub, and coastal dunes from the Carolinas to Florida and Texas. Its sharp-toothed leaf stalks (the "saw") arch out in stiff fans, and in fall it ripens hanging clusters of dark, olive-like berries that are its harvested part and a well-known herbal extract. Extremely tough, fire-adapted, drought- and salt-proof, and astonishingly long-lived (some clumps are centuries old), it is grown for those berries and as a rugged evergreen landscape palm - but it is hardy only in warm zones, roughly 8 and up.

Saw palmetto grows in full sun to part shade in sandy, well-drained soil and tolerates drought, salt, poor ground, and even occasional flooding once established. It is famously slow - both to establish and to grow - so start with a container plant and be patient, as it resents transplanting from the wild. Plant in spring in a warm spot; water through establishment, then it needs little. It is hardy only in zones 8 to 11; in colder areas it is not winter-hardy in the ground. Mind the sharp leaf-stalk teeth when siting and tending it. Once settled it is essentially permanent and care-free.

Established saw palmetto has few problems and needs little intervention
Harvest the berries (drupes) in fall, from about August to October, when they ripen from yellow-green to brownish-black; pick them from the clusters, minding the saw-toothed leaf stalks. They are traditionally dried for use as the well-known extract. The plant is slow to come into bearing, so harvest from established clumps. Dry the berries thoroughly. Note that wild harvest of saw palmetto berries is regulated in Florida and requires a permit, so grow your own or buy responsibly.
Saw palmetto is grown for its berries, traditionally dried and made into the well-known herbal extract rather than eaten as a fruit (fresh berries are strongly flavored and not a dessert food). The palm itself is a tough, evergreen, fire- and salt-adapted native for warm-climate landscapes and a valuable wildlife and honey plant, its flowers feeding bees and its fruit feeding many animals.
