Living along the coast certainly has its advantages: access to the beach every day, coastal breezes, mild temperatures, fresh seafood and pretty views.
However, gardening in these environments can present a challenge. While saltwater has its benefits, most plants and flowers don’t like it. Salinity in the soil inhibits a plant’s ability to absorb important nutrients, thereby disrupting the plant’s metabolism.
Finding salt tolerant plants to for your lawn can be a challenge. In many cases, you can select salt tolerant varieties of ceratin plants which can do well in coastal climates. The salt tolerance of plants is determined by a variety of factors, including a plant’s ability to grow under and resist high winds, salt spray, alkaline soils and infertile, sandy soils.
When choosing plants that will be placed facing the ocean without buildings to protect them, you should choose highly salt tolerant plants. If the plants are protected by a building, you can get away with selecting types that are only slightly salt tolerant.

Salt Tolerant Shrubs
Salt tolerant shrubs can deliver a big impact, depending on how big they get. Finding a variety that you love can transform your yard into a beautiful oasis.
Oleander is a favorite shrub for coastal living. Not only are oleanders salt tolerant, but also they are heat tolerant, survive in full sun and thrive in a variety of soils while producing beautiful blooms. Different varieties can grow to a height of 10 feet and 8 feet wide, so they can cover a large area for just one plant.
Other highly salt tolerant shrubs that like sun or part shade include these varieties:
- Century Plant (Agave americana)

There are just a few highly tolerant flowers, such as the Blanket Flower Gaillardia, Daylily, Lantana, Prickly Pear Cactus, Lavender Cotton and Seaside Goldenrod. When you are making your selections, just keep in mind other important factors in your yard, such as the amount of sun the area gets, as well as how much water the plants need.

Looking to put it all together? Now, let’s talk about beach landscaping ideas.
Salt Tolerant Plants for Beach Landscaping
In addition to all the salt tolerant plants we have listed about, you’ll probably also want to think about turf grasses, groundcovers, vines and trees. All of these types of plants thrive better than flowers in these environments.
Turfgrasses such as Seashore Paspalum have a very high salt tolerance and moderate drought tolerance and prefer sunny conditions. Hybrid and Common Bermuda, as well as Zoysia grasses, all have a high salt and drought tolerance, which is one reason you tend to see them in coastal areas.
If you are in search of a salt tolerant groundcover, you might consider trying:
- Asparagus Sprengeri Fern (Asparagus densiflorus)
- Algerian Ivy (Hedera canariensis)
- Goats-foot Morning Glory (Ipomea pes-caprae)
- Trailing Lantana (Lantana montevidensis)
- Virginia Creeper (Parthenocissus quinquefolia)
- Stonecrop (Sedum varieties)
- Asiatic Jasmine and Confederate Jasmine (Trachelospermum asiaticum, Trachelospermum jasminiodes)
- Wedelia (Sphagneticola trilobata)
- Shore Blue Pacific Juniper (Juniperus conferta)
- Lily Turf Liriope (Liriope muscari)
- Japanese Purpleleaf Honeysuckle (Lonicera japonica ‘Purpurea’)
- Mondo Grass (Ophiopogon japonicus)
Vines, which can sometimes serve as groundcover can help add color to your outdoor areas. If you have an idea which would work well for this type of plant, you might consider:
- Virginia Creeper (Parthenocissus quinquefolia)
- Cape Honeysuckle (Tecoma capensis)
- Bougainvillea (Bougainvillea varieties)
- Trumpet Vine (Campsis radicans)
- English Ivy (Hedera helix)
- Coral Honeysuckle (Lonicera sempervirens)
- Fig Ivy/Creeping Fig (Ficus pumila)
- Carolina Jessamine (Gelsemium sempervirens)
English Ivy needs shade, so if you opt for this plant, make sure it isn’t in full sun.
If you’d like to add height or shade to your yard, you might want to add a tree which can tolerate salty conditions. A few we suggest are:
- Chinaberry Texas Umbrella (Melia azedarach)
- Huisache (Vachellia farnesiana)
- Texas Persimmon (Diospyros texana)
- Southern Golden Raintree (Koelreuteria bipinnata)
- Mulberry (Morus alba)
- Mesquite (Prosopis glandulosa)
- Lavender Chaste Tree Vitex (Vitex agnus-castus)
- Camphor Tree (Cinnamomum camphora)
- Citrus (Cleopatra mandarin)
- Loquat (Eriobotrya japonica)
- Retama (Parkinsoia aculeata)
- Japanese Black Pine (Pinus thunbergii)
Large Trees, including the Australian Pine, Tamarisk Salt Cedar, Deodar Cedar, Arizona Cypress, Live Oak, Eucalyptus, Cottonwood and Bald Cypress also do well along the beach. Of course, if you want to go with a typical tropical landscape, then the Palmetto, Texas Palmetto, Cabbage or Florida Palmetto, Washington Fan Palm, Pindo Palm, European Fan Palm and Phoenix or Canary Island Date Palm work well along our Texas beaches.
If you have an area that gets hit with strong winds or experiences a good amount of sea spray, you might want to consider adding Sea Coast Blue Stem, Salt Grass, Lindheimer’s Muhly Grass, Sand Knotgrass, Fountain Grass and Giant Seaoats to your lawn and garden.
Salt Tolerant Tropical Plants
If you want a more tropical look for your landscaping, you have plenty of options. You will still need to take into account which types are shade tolerant and which plants need sun, depending on the conditions in the area you want to plant.
Palms are the most obvious addition to turn your property into a tropical oasis. Whether it’s a large Sabal Palmetto or a smaller Saw Palmetto, these plants are adapted to flourish in coastal areas.
Ornamental grasses like the Sand Cordgrass work well along the coast when paired with Oleander, Bougainvillea and some of the perennials below. A combination of these plants can help you create a pretty tropical escape.
Tropical perennials that do well at the beach include:
- Wright’s Texas Firecracker (Anisacanthus wrightii)

Another option is to use containers for your landscaping so that you can bring these plants inside to control the salinity of the soil. By using this approach, you can have the flexibility to use lower salt tolerant alternatives to what species might work well in other areas. You can also change the salinity of the soil or build a fence or other barrier to help protect the plants to increase the variety of plants you may choose for your beachside home.
