Saw Palmetto Palm Tree Info
Scientific name: Serenoa repens or Sereno repens
Common names: The Saw Palmetto is also known as Silver Saw Palmetto Palm and Scrub Palm.
Origin: It is native to Florida and grows all over the southeastern United States.
Appearance: It can spread up to 20ft or more in diameter. It grows as a shrub with stems occurring below the ground or runs along the ground, creating a dense ground cover. Stems gradually bury to form rhizomes. Stems sprouted from rhizomes can measure 10 to 15 feet in length. Occasionally, it develops an erect or arching trunk that is covered with old leaf bases.
Each clump has about 20-25 large palmate, fan-shaped, leaves, that are supported by 2ft long, petioles. Stems are armed with very sharp spines, hence the name Saw Palmetto Palm. Leaves are evergreen, stiff, about 3ft across, covered with waxy film, with 18-20 leaflets. The common Saw Palmetto has green leaves but there are some silvery-green leaved types as well.
Flowers/Fruits: During spring the Saw Palmetto Palm produces small, yellow-white, fragrant flowers that are growing in dense clusters. Flowers are supported by 3ft long branched inflorescence emerging from the leaf bases. The Saw Palmetto Palm flowers are a great source of commercial high-grade honey. Flowers are followed by yellowish-green fruits that gradually turn blue-black as they ripen August through October.
Fruits are small, berry-like, oval, and fleshy. These berries are an important food source for many mammals and birds. The berries have been used for medicinal purposes helping to treat some prostate and urinary problems.
Growth Rate: Slow. Serenoa repens is a small hardy palm that can grow up to 5-10ft tall and 1-5 ft wide.
Outdoor/Indoor Use: Both.
Cold Tolerance: The Saw Palmetto Palm is one of the cold hardiest palm trees that can tolerate cold down to 0F. It is great for growing in the USDA Zones 7a (0 to 5 F) to 11 (above 40 F).
