Common name
cabbage palm, sabal palmetto, sabal palm
Description
Stems: Solitary, upright stems to 20 m tall and to 35 cm diameter. Leaves: Old leafleaf:
in palms -- the leaf blade (which is usually divided into leaflets or leaf segments), the petiole (or leaf stalk) and the sheath (which forms the attachment of the leaf to the stem)
bases often persistent, but can fall away to leave a smooth stem. Costapalmatecostapalmate:
a fan-shaped leaf with a midrib (costa) extending into the blade, sometimes extending far enough into the blade to cause it to curve (e.g., <em>Sabal palmetto</em>)
leaves with a strongly arching costacosta:
mid-rib or vein
. Leafleaf:
in palms -- the leaf blade (which is usually divided into leaflets or leaf segments), the petiole (or leaf stalk) and the sheath (which forms the attachment of the leaf to the stem)
segments rigid, with numerous fibers along the segment margins. Petiole bases split. Flowers and fruits: Inflorescences equaling or exceeding the leaves in length, branched to three orders. Flowers creamy white, bisexual. Ripe fruit black, spherical to a slightly flattened sphere (pear-shaped), 8-14 mm diameter, usually about the size and shape of a medium blueberry.

May be confused with
Sabal minor, in that a young Sabal palmetto can grow many years before its stem rises above ground. A young S. palmetto can be distinguished from S. minor, which has a true underground stem, by the prominence of the curved shape of the S. palmetto costapalmatecostapalmate:

Distribution
Native to Bahamas, Cuba and southeastern United States from North Carolina to Florida
Additional comments
If the palm has been severely pruned, with only 2-3 leaves remaining, inflorescences may droop well below the leaves.
This palm is the state "tree" of South Carolina and Florida.
