Ecology

Habitat

In the Coastal Plain in Florida and Georgia, Serenoa repens has occurred around sinkholes in oolite, on dunes in an understory of Pinus clausa, sandpine-evergreen oak scrubs, cabbage palm-hardwood hammocks, pine flatwoods, open slashpine woodlands, coastal hammocks, Baccharis flats, longleaf pine-scrub oak ridges, dried up ponds, and pine-oak woodlands. It has been found in disturbed areas such as open pastures, roadsides, and a newly planted slash pine plantation with deep sterile sandy soil (FSU Herbarium). Soil types include sand and loamy sand (FSU Herbarium). Associated species include Persea, Rapanea, Myrica, Ficus, and Ardisia (FSU Herbarium).
