Cabbage palmetto cold hardiness
Sabal palmetto (Walter) Lodd. ex Schult. & Schult.f.
Outdoor verdict
Cabbage palmetto lives outside where winter stays above about 15F (USDA 8a+). If your winter drops below that, skip it. Do not wrap a tropical and hope.
The native cabbage palmetto of the Southeast. USDA 8a to 11, costapalmate fans, and a much hardier street tree than royal or coconut.
Cold hardiness
Survives about 15°F / -9°C. Outdoor range USDA 8a–11a. Hover or click a zone, state, or country. Click a state to open palms that grow there.
Highlighted USDA zones 8a–11a. Green countries can be grown outdoors.

Native Can be grown
Alaska and Hawaii are state outlines with their overall zone range. A country is painted if its mildest inhabited winter is at least one USDA step milder than this palm’s hardiness.
What it is confused with
Nurseries often mix this up with Saw palmetto (Serenoa repens). Check the Latin on the tag.
Winter care
Drainage matters more than a blanket. Soil: Any well-drained soil. Water: Moist but never waterlogged (mesic). A young plant sees more damage than an old one. Wrap only when a night near the kill number is coming.
Scientific facts
- State tree of Florida and South Carolina.
- Costapalmate leaves: a fan with a midrib that extends into the blade.
- Boot jacks (old leaf bases) often stay on the trunk for years.

Full care guide
Cabbage palmetto is the native street palm of the southeastern coastal plain, not an import trying to look like Miami. USDA 8a to 11. It takes freezes that would finish a royal or coconut, and it is the state tree of Florida and South Carolina.
Growth Rate:
Slow to moderate. Faster in frost-free south Florida than in zone 8b.
Fruit and Flowering:
Black fruit that wildlife eats. Seedlings show up in beds if birds sit above them.
Light Requirements:
Full sun. Young plants take some shade.
Water Requirements:
Regular water to establish. Native sites range from moist to seasonally dry. Do not keep it in a sealed wet hole.
Maintenance Level:
Low to medium. You can leave boots or clean the trunk. Feed in the growing season with palm-specific fertilizer in sand. Hurricane-broken fans are a cleanup job.
Common Diseases/Pests:
Palmetto weevil on stressed or newly transplanted trees, scale, and occasional leaf disease in still shade. Plant healthy, water, and do not butcher the crown.
Plant Care:
Plant in sun with drainage. Water the first year. Use this when you want a native Southeast palm, not a coconut in a climate that still freezes.
Cabbage palmetto Frequently Asked Questions:
If you garden on the southeastern coastal plain, cabbage palmetto is the native tree palm to learn first. Save royals and coconuts for the places that never freeze.
Cabbage palmetto questions
Will Cabbage palmetto live outside?
Yes, if winter stays above about 15F (USDA 8a+). Below that number it belongs in a pot.
What do nurseries mislabel Cabbage palmetto as?
People tag it as Saw palmetto. That plant is Serenoa repens. Check the Latin.
Pot or ground for Cabbage palmetto in a cold state?
Ground where winter stays above about 15F. A pot does not make a cold-tender palm hardy. Skip it if the number fails.
Is cabbage palm the same as palmetto?
Cabbage palmetto is Sabal palmetto, a tree. Saw palmetto is Serenoa, a shrub. People say palmetto for both.
Can I grow it in Atlanta or Dallas?
Dallas has used it in warm sites. Atlanta is the cold edge. A hard zone 7 winter is a risk. Windmill and needle palm are safer there.
Why did a newly planted sabal die?
Weevil on a stressed transplant is a classic. Plant in the warm season, water, and do not overprune the head.
Does it grow fast?
Not like a queen palm. Budget years, not months, for a trunk.
