Turf Classification & Certification

Supreme Paspalum is a proprietary Seashore Paspalum variety certified by the Southern Seed Certification of America, ensuring genetic integrity, consistency, and performance across all installations. It is distributed exclusively through South Florida Grassing.

Comparative Differentiation: Supreme Paspalum is not a blended product or a generic paspalum selection. It is a specifically developed cultivar evaluated for commercial turf use on golf courses, resorts, and large-scale developments.

Quick Facts

  • A golf course with sand bunkers, green grass, and a clear blue sky, located near residential buildings and tall palm trees in the background.

    Turf Performance & Playability

    Consistent playing surface: Recognized for rich dark green uniform growth and a dense canopy that support a consistent playing surface, contributing to reliable playability and strong visual quality across maintained turf areas.

  • A lush green golf course with a sand trap, a water fountain, and a flag on the putting green under a bright blue sky with scattered clouds.

    Traffic Recovery

    Recovery from wear and use: Recovers effectively from traffic and wear, supporting consistent turf conditions in high-use environments such as golf courses and resort properties.

  • A lush green golf course with a putting green, sand trap, water fountain, trees, and a bright blue sky with a few clouds.

    Maintenance & Management Profile

    Efficient professional maintenance: As a semi-dwarf cultivar, requires less frequent mowing and lower irrigation than other commercially grown paspalums and carries a low nitrogen requirement — delivering durable, long-term performance under professional turf management and consistent use.

  • A golf course with a putting green and a person riding a golf cart near a pond, with a large white residential building with red roofs in the background under a clear blue sky.

    Salt Tolerance

    Outstanding salt tolerance: Among the most salt-tolerant turfgrasses available — performing under saline, reclaimed, and poor-quality irrigation, including freshwater–seawater blends, and withstanding occasional seawater inundation while maintaining turf quality and density in coastal environments where salt exposure limits traditional turfgrass.

  • Sweeping view of a lush, manicured golf course with rolling green hills and sunlight casting soft shadows on the grass.

    Climate Adaptability

    Year-round climate adaptability: Performs consistently in hot, humid climates and holds turf quality under extended heat stress, while retaining color through the cooler months and tolerating lower temperatures — resulting in reduced nitrogen requirements. Adapts to both full sun and moderate shade.

  • A golf course with lush green grass, a sand trap, trees, a water fountain, and a club house in the background under a bright blue sky with scattered clouds.

    Soil & Water Conditions

    Adaptable to challenging site conditions: Establishes in sandy or infertile soils and maintains stability under variable, low-quality water — including reclaimed sources and periodically waterlogged or inundated sites — making it suitable for locations with environmental or infrastructure constraints.

  • A golf course with well-manicured green grass, tall palm trees, and a luxurious building with red-tile roofs in the background under a clear blue sky.

    Stress Resistance & Durability

    Designed for demanding conditions: Withstands high traffic, intensive use, and environmental pressure while maintaining performance in professional turf applications.

How Supreme Paspalum Compares to Platinum

Documented in the competing cultivar's own U.S. plant patent.

Metric Supreme Paspalum Platinum (TE-13)
Salt tolerance9.0 — highest7.5
Establishment / grow-in9.0 — fastest8.0
Turf quality (Mid-FL)1.59 — best1.75
Turf density1.21 — tightest1.50
Seed-head expression1.00 — fewest1.63

Higher is better for salt tolerance and grow-in; lower is better for quality, density, and seed-head ratings — Supreme leads in every category.

Sustainability & Resource Efficiency

Supreme Paspalum is engineered to deliver premium performance on fewer resources - an advantage that grows more decisive as water is restricted, input costs rise, and environmental standards tighten.

Water Efficiency

As a semi-dwarf cultivar, Supreme requires less irrigation than conventional paspalums and many hybrid turfgrasses, lowering both water consumption and operating cost.

Reduced Nitrogen Requirements

A low nitrogen requirement means less fertilizer across the season, supporting leaner maintenance programs and reduced nutrient runoff.

Flexible Water Sources

Supreme performs reliably on reclaimed, brackish, and poor-quality water, from recycled irrigation to freshwater–seawater blends — well suited to sites where potable water is limited or restricted.

Winter Color Retention

Supreme carries strong color deep into the cooler months, keeping turf presentable and playable through the off-season with no added inputs.

Intended Use & Project Scale

Supreme Paspalum is intended for high-value, professional turf applications where performance, durability, and consistency are critical. It is well-suited for:

• Golf courses

• Destination resorts

• Coastal and waterfront developments

• High-end commercial landscapes

• Luxury private estates with professional maintenance

Supreme Paspalum was developed for large-scale, high-performance projects and the properties that demand the same standard. While it isn't a fit for the average do-it-yourself homeowner, it thrives when backed by a professional maintenance program.
