Seashore Paspalum
Learn why seashore paspalum is associated with salt-affected sites, how it is managed, and what NTEP evidence PoaIndex indexes.
Seashore paspalum is a warm-season turfgrass associated with coastal and salt-affected sites. Salt tolerance is its distinguishing agronomic story. It is not a low-water grass for every warm climate, and it is not a substitute for ordinary bermudagrass lawns inland.
Quick facts
| Topic | Reviewed context |
| -------------------- | ---------------------------------------------------------------- |
| Season | Warm-season |
| Distinguishing trait | High tolerance of soil and irrigation salinity |
| Climate | Southern / coastal warm-season use |
| Establishment | Mostly sod, sprigs, or plugs; a seeded cultivar exists |
| Maintenance | Moderate; not a neglect-and-forget lawn |
| Drought | Fair to good in Clemson’s comparison table — not “no irrigation” |
| Common use | Coastal lawns, golf and sports turf where water is salty |
Where it generally fits
Clemson Extension’s lawn-grass guide lists seashore paspalum among southern turf options and rates its salt tolerance as excellent. The same table places it on salty soils, with sod, sprigs, or plugs as the usual establishment methods and a moderate maintenance level.
Texas A&M AgriLife is more geographic: because seashore paspalum does not tolerate prolonged low temperatures, it is best adapted to the southern third of Texas. AgriLife describes it as tolerant of salinity in both soil and irrigation water, suited to sports turf, golf fairways, and high-maintenance lawns where irrigation salinity is a concern, and notes that seed and sod are less readily available than for other grasses.
University of Georgia coastal county guidance includes seashore paspalum among coastal Georgia summer lawn options. That is a coastal recommendation, not a statewide default.
PoaIndex will not treat salt tolerance as a reason to recommend the species in a ZIP where the turf-zone baseline says it does not belong.
Growth and lawn characteristics
Salt tolerance is the reason this grass is discussed at all. Clemson’s saltwater-intrusion fact sheet calls seashore paspalum the best warm-season turfgrass for salt tolerance and a possible option where saltwater intrusion is frequent. Zoysia, bermuda, and St. Augustine are described there as having fairly good tolerance; centipede is poor.
Salt tolerance is not a license to skip irrigation. Clemson’s selection table rates drought tolerance only fair to good—below bahiagrass and bermuda in that comparison. Texas A&M highlights saline _irrigation water_ as a use case, which still assumes the turf is being watered. If the site is dry but not salty, another warm-season grass may be the more straightforward choice.
Management is real work. Clemson lists a moderate maintenance level and a mowing height around 1 to 1½ inches. Texas A&M recommends about 1 inch or less and says paspalum needs less nitrogen than improved bermudagrasses. UGA coastal mowing notes also place seashore paspalum in a 1–2 inch band. Those are managed-turf heights, not a meadow.
Establishment is mostly vegetative. Clemson lists sod, sprigs, and plugs. Texas A&M names several vegetative cultivars and Sea Spray as a seeded variety, while warning that neither seed nor sod is as readily available as for other grasses. Cultivar identity matters because availability and use (lawn versus golf) differ.

Why cultivar choice matters
NTEP evaluates individual seashore paspalum entries. Vegetative specialty cultivars and a seeded type are not the same product. Quality, texture, and management response can differ even when every entry shares salt tolerance as a species story.
PoaIndex ranks within seashore paspalum only. AOSCA identity may affect display names when confirmed. Historical NTEP commercial markers are not a list of what is in production now.
See How to Read NTEP Ratings and NTEP Commercial Availability.
Can I buy the cultivars shown in NTEP?
Less often than for Kentucky bluegrass or tall fescue. Texas A&M notes limited seed and sod availability. Trial lists also include experimental entries. PoaIndex does not claim you can buy a ranked cultivar this week.
If the species is suitable for your ZIP, treat the shortlist as names to research with a specialty grower.
Common questions
Why is seashore paspalum associated with salt tolerance?
Because Extension sources rank it at the top of common warm-season lawn grasses for salt. Clemson calls it the best warm-season choice where saltwater intrusion is frequent. That is about surviving salt in soil or irrigation water—not about growing without water.
Where is seashore paspalum commonly used?
Coastal and southern sites, plus golf and sports turf where irrigation water is saline. Texas A&M limits its Texas adaptation to the southern third of the state because of low-temperature sensitivity.
Does seashore paspalum require special management?
It is a managed turf, not a wild coastal planting. Mowing heights are relatively low, fertility still matters, and Clemson rates maintenance as moderate. Salt-tolerant does not mean unkillable.
Does cultivar choice matter?
Yes. Planting method, availability, and turf use vary. NTEP exists to compare those entries at real locations.
What NTEP evidence does PoaIndex index?
Historical Turfgrass Quality from the reviewed seashore paspalum report plan, shown in the evidence summary on this page. Rankings for a specific ZIP still come from the interactive product.
