Classify the property’s salt exposure
A Gulf-front lot, a home behind dunes and a protected interior neighborhood do not receive the same salt load. UF/IFAS recommends at least some salt tolerance for plants installed within roughly one-eighth mile of saltwater coasts, but direct aerosol exposure can demand the toughest material.
Trees and palms for structure
Cabbage palm, saw palmetto, southern red cedar and appropriately placed live oak can provide coastal structure. Southern magnolia has only moderate salt tolerance and is better protected from direct coastline exposure. Mature size, utilities and wind structure still control placement.
Screening and foundation plants
Wax myrtle and yaupon holly can work as screening elements when allowed enough room. Coontie offers a lower evergreen layer. Avoid selecting by nursery size; repeated shearing is a predictable cost when the mature plant is too large for the bed.
Grasses, flowers and groundcovers
Muhly grass, Fakahatchee grass, beach sunflower, gaillardia, seaside goldenrod and railroad vine can fit selected coastal conditions. Sea oats and dune vegetation may be regulated or ecologically sensitive, so dune work requires appropriate guidance and authorization.
Turf near salt spray
UF/IFAS identifies St. Augustinegrass and zoysiagrass among the better homeowner choices for some salt exposure. They tolerate salt spray differently than saltwater irrigation; neither should be treated as a lawn that can be watered with seawater.
Establishment still determines success
Salt tolerance does not eliminate the need for correct planting depth, root-zone water and drainage. Inspect irrigation before planting, protect the root ball from drying and gradually adjust watering as roots establish.
Design for wind and maintenance
Layer sturdy plants to reduce wind exposure, keep sightlines and building clearance open, and avoid loose decorative material in vulnerable areas. A natural plant form usually handles coastal conditions better than constant tight shearing.
Use a property-specific plant schedule
Specify common and botanical names, installed sizes, quantities, spacing, exposure zone and substitutions. That prevents a generic ‘salt-tolerant’ package from becoming a mix of plants with very different tolerances.
