The best another name for St Augustine grass to know is its Latin name: Stenotaphrum secundatum. You'll also hear it called buffalo grass, buffalo turf, carpet grass, and Charleston grass. All these names point to the same thick, warm-season turf.
The st augustine grass scientific name shows up on sod labels and herbicide bottles. I learned why this matters after buying a weed killer that said "safe for warm-season grasses" on the front. The back label listed Stenotaphrum secundatum as a grass it would harm. If I had only looked for "St. Augustine" on that label, I would have missed the warning and killed my own lawn.
This grass picked up different names as it spread across the world over hundreds of years. NC State traces it to the Southeast USA, South America, and Africa. Each region where it took root gave it a local name based on how it looked or where it grew. The grass kept spreading along warm coasts, and the list of nicknames grew with it. You can find this same species growing wild on sandy beaches on three separate continents today.
The names charleston grass buffalo turf come from two sides of the globe. Charleston grass is an old name from the Carolina coast. Older folks in the coastal South still use it today. Buffalo turf is what you'll hear in Australia and South Africa. In the Caribbean, people call it "mission grass" or "carpet grass" based on how it creeps flat across the ground. You can see why this gets confusing fast when you're reading lawn tips from writers in different countries.
This naming mess creates real issues when you shop for products or read care tips online. An Australian post about "buffalo turf" is talking about St. Augustine. A Texas store selling "carpet grass" might mean a different species from what you expect. Your safest bet is to use the Latin name when you talk to sod growers or extension agents. That way you get the right product every time.
In my experience, saving the Latin name in your phone helps a lot at the garden center. Check whether "buffalo grass" in any article means your St. Augustine or the North American prairie grass. This one small step keeps you from buying the wrong herbicide or sod. Getting it wrong could set your lawn back a full growing season. You also want to double-check fertilizer rates since they differ between grass types. The right name gets you the right care every time.
