Salt Tolerant Plants in Florida for Coastal Yards

For salt tolerant plants in Florida, UF/IFAS's salt-tolerant list includes beach sunflower, sea oats, sea grape, coontie, cabbage palm and saw palmetto, and it rates cabbage palm and saw palmetto highest. It says anything planted within about an eighth of a mile of saltwater needs at least some salt tolerance. On a barrier-island lot, choose plants with the top ratings; on the mainland, moderate ratings are an option.

Xtreme Scapes installs plantings as part of landscape installation in Brevard County: soil prep, new beds, and shrubs, groundcover, palms and trees set in the ground. This guide covers the plant choice, so you know what to ask for before anyone digs.

How far the salt reaches in Brevard

Wind, salt and sandy, high-pH soil are the three coastal pressures UF/IFAS lists.

A Rockledge nursery writes that those on the barrier island or Merritt Island have much higher sand content, which does not hold moisture as well and tends to be on the alkaline side. The same post says newer developments, and it names Viera, tend to have less organic matter in the topsoil. It also says salt spray is quite likely if you are only a few blocks from the coast.

The table below sorts the list by exposure.

Salt tolerant plants by exposure

The table uses UF/IFAS fact sheets. The rating column quotes each sheet. The last column is a suggestion, not an IFAS category: IFAS does not sort plants by Brevard town. IFAS rates some plants for salt spray on the leaves and others for salt in the soil, so the wording differs by row.

Two more plants on the UF/IFAS list come with a limit. UF/IFAS calls bougainvillea "only moderately salt tolerant" and says it suits landscapes "a little further inland." It says Southern magnolia is moderately salt tolerant but "shouldn't be planted on the coastline". Both belong back from the water.

Oceanfront and barrier-island plants

Start with natives that already live on the dune. The Indian River County Extension office names railroad vine, beach sunflower, sea oats, spider lily and sea grape as salt-sprayed-coast natives. It says sea oats are often found in large colonies at the very top of the sand dune, and that it is illegal to pick sea oats, because they are an endangered plant needed for dune stability.

For structure behind the dune, the palms are the strongest choice. UF/IFAS says palms are all at least moderately salt tolerant, and the highest tolerance is found in native cabbage palms and saw palmettos. The saw palmetto sheet also lists its hurricane tolerance as high.

The sabal caution matters on canal and river lots. The sheet says it is intolerant of salt in the root zone. Ask the nursery whether salt water reaches the soil on your lot before you choose a sabal.

For low color and groundcover, UF/IFAS lists beach sunflower, gaillardia and seaside goldenrod as wind and salt tolerant, and railroad vine and gopher apple as dune stabilizers. Wind is part of the problem too. UF/IFAS suggests you create wind screens with fences, sturdy shrubs or groups of trees to protect the plants behind them.

Sheltered mainland plants

Away from the water, the palette opens up. Muhly grass, coontie and saw palmetto still work. The list also calls live oak and southern red cedar "always safe choices" for trees, and names hibiscus, firebush, plumeria and sterile lantana varieties for flowering shrubs.

Read the firebush row twice. The UF/IFAS list names it as a coastal flowering shrub, but the firebush fact sheet rates soil salt tolerance as poor. Treat it as a plant for the mainland side of the line, where spray is light and the soil is not salty. If a lot sits right at the water, choose something else for that bed.

Coontie suits a dry bed. Its sheet rates drought tolerance as high, and UF/IFAS says grouping plants with similar water needs makes it easier to give your plants the correct amount of water. Keep it out of a bed with plants that need frequent water.

Cold limits: sea grape and silver buttonwood

Salt is only one limit. Cold is the other.

The UF/IFAS Brevard County office says that on the mainland, from Scottsmoor down to Micco, "we are considered zone 9b." It adds that South Merritt Island and the beaches are typically zone 10a, "but that is not always the case, as this winter proved." The same post names firebush among the native plants the February 2026 freeze hit, though it says natives "should survive even if they look horrible now."

Now compare the fact sheets. UF/IFAS lists sea grape for USDA zones 10A through 11 and silver buttonwood for zones 10B through 11. The buttonwood sheet gives it a high aerosol salt rating, so on salt alone it looks perfect. Check those zones against your lot before you buy silver buttonwood (10B to 11) or sea grape (10A to 11). The Brevard office puts the mainland in 9b and the beaches typically in 10a.

Right plant, right place

The first Florida-Friendly Landscaping principle is right plant, right place. UF/IFAS says "a complete site analysis should be conducted and followed when plants are chosen," and that plants matched to their site mature to the desired size and "will require less pruning."

In Brevard, the site analysis starts with the two items above: how close the water is, and which zone the lot sits in. Ask the nursery or contractor for both before you agree to a plant list.

Mulch

UF/IFAS says two to three inches of an organic mulch should be applied and replenished as needed, and mulch should be pulled back 1 to 2 inches from the base of plants. For trees, it says to avoid "volcano mulching" because mulch piled against the trunk holds moisture and encourages rot.

Newly planted salt-tolerant plants still need fresh water at the start. UF/IFAS says coastal plants need fresh water to thrive, and fresh water during the establishment period, or during times of stress, can make all the difference.

What to skip near the water

Skip these near the water: southern magnolia on the coastline, bougainvillea on the oceanfront side of the lot, and firebush, whose fact sheet rates soil salt tolerance poor.

If a plant has no salt rating you can find, treat it as unproven and ask your county Extension office, which the UF/IFAS pages recommend for varieties that perform best in your area.
