What Makes It Different
This is the only way to plant paspalum without buying sod, and it exists because of a genetic quirk worth understanding.
Almost every improved seashore paspalum is self-incompatible — the plant can’t fertilise itself, so it makes no viable seed. That’s why the good cultivars come only as sod or sprigs, and why they’re patented, licensed and expensive to move. The seeded types are the rare exceptions bred around that limitation.
The practical payoff is logistics. Seed ships in a bag. Sod ships as a perishable pallet with a minimum order, and freight can cost more than the turf itself once you’re any distance from Georgia, Florida or California. If you’re outside the sod belt, seed isn’t the cheap option — it’s the only option.
What you pay for that is time and uniformity. Seed germinates in 10 to 17 days, and only once soil is above 60°F. It comes in unevenly, it can throw off-type plants, and it takes two to four months to reach full cover against four to six weeks for sod or sprigs. Through all of that, weeds have an open door.
Who It’s For
The big coastal lot — an acre of salt-affected ground where sodding is simply not a number you’re willing to write down. Or the coastal homeowner far enough from a licensed grower that nobody will deliver a residential-size order at all.
You need to be able to accept a patchy first season, and you need a fresh-water source for the grow-in. If you want a lawn this month, or you’re patching a small area, sod from one of the other paspalum pages is the better answer.
The Cultivars
The seeded market went through a full generational change, and the roster name most people search for is no longer sold.
| Cultivar | How it’s sold | What it’s good at | Notes |
| Pure Dynasty | Seed, through Justin Seed, Atlas Turf International, Pure Seed and authorized distributors. “Call for price” | The current standard. A blend of improved seeded cultivars rather than one clone — the breeder reports faster establishment, tighter density, better disease resistance and improved spring green-up, with Platinum TE as one genetic parent | Florida, Gulf South, Texas Gulf, coastal California, Hawaii. Packaged for residential lawns, but ordered from seed distributors, not garden centers |
| STRATIS with ACCe (announced as Pure Dynasty with ACCe) | Seed, exclusively through Atlas Turf International, Pure Seed and licensed distributors | Carries the non-GMO ACCase-resistance trait — you can spray sethoxydim, fenoxaprop or pinoxaden to kill invading bermudagrass without harming the lawn. This is the biggest change to paspalum’s home-lawn viability in years | Entered commercial production in late October 2025 and supply has been tight, with distributors prioritising golf and stadium projects. Registered for lawns. Ask about availability before planning around it |
| Sea Spray | Discontinued | Was the first improved seeded paspalum, introduced in 2003 | Our sourcing research found no active seller, and the current seed marketer describes Pure Dynasty as the only seeded paspalum on the market. If you’re offered Sea Spray, ask hard questions about the seed’s age |
One lead we couldn’t verify: at least one turf brand sells consumer-packaged paspalum seed in one-pound containers, which would be the easiest residential purchase in the species. It sits outside our sourcing research and we can’t confirm which cultivar or blend is in the bag — so ask before you buy.
What Changes In Care
Established seeded paspalum is cared for exactly like the type page describes. Everything different happens in the first season.
- Sow in late spring or summer, once soil holds above 65°F and air above 70°F. Below 60°F soil, seed won’t germinate.
- Product labels for the current blend call for roughly 1.5 to 3 pounds of coated seed per 1,000 sq ft for a new lawn. Coated seed weighs more than raw seed, so don’t convert rates between the two.
- Light and frequent — as often as four to six times a day for the first few weeks to keep the surface damp. Use fresh water only. Salty or recycled water stalls root growth in young paspalum even though the mature lawn drinks it happily.
- Feed gently, and check the type. Young paspalum reacts badly to ammonium fertilisers, so use a nitrate source at about a quarter to half a pound of nitrogen per 1,000 sq ft, with phosphorus at least equal to nitrogen to drive rooting.
- No pre-emergent weed killers for about three months. The products that are safe on mature paspalum are lethal to seedlings — they stop exactly the root growth new plants depend on. During grow-in your only weed defences are competition and the few establishment-safe products; quinclorac and mesotrione have research support at planting.
- No salt. The salt-as-weedkiller trick that makes this species famous will kill your seedlings along with the weeds. It’s a tool for an established lawn only.
Before You Buy
- Prepare the site properly, because you can’t spray afterward. Clear the weeds before you sow. That three-month herbicide window is the single biggest reason seeded lawns come in weedy.
- Check the seed tag — purity percentage, germination percentage, and the test date. Paspalum seed has a real shelf-life problem; one licensed distributor tells buyers to contact them for availability specifically because of it. Old seed is the quiet way this fails.
- Order early. This is not a garden-center product. Expect commercial seed distributors, quotes rather than shelf prices, and lead time — especially for the ACCe seed, which has been in short supply since launch.
- Expect off-types. Pure Dynasty is a blend, not a clone, so a seeded stand won’t have the uniformity of a vegetative cultivar. That’s the trade, not a defect.
- Verify the species. You want turf-type Paspalum vaginatum, not bahiagrass ( notatum) or thin paspalum (P. setaceum), which stay coarse and open and never form a lawn.
- Clearing an old lawn first? Allow the full 14 days before sowing, and check the active-ingredient panel — consumer “Roundup” no longer reliably means glyphosate, and replant intervals differ by active ingredient.

How to Kill Weeds in New Grass Without Killing the Grass
You spent weeks preparing the soil and watering your new seeds, only to see a "carpet of green" that looks more like a weed patch than a lawn.
