Variety Traits

Drought Tolerance

With water becoming an increasingly precious resource, TWCA® qualified turfgrass varieties offer a sustainable solution. They require up to 40% less water than conventional varieties, helping to conserve this vital resource without sacrificing a beautiful lawn. 

Traffic Tolerance

PST utilizes a traffic simulator to assess the impact of traffic on different types of turfgrasses, simulating the wear and tear of a real game. 

Disease Tolerance

Our turfgrass varieties undergo rigorous screening under the most intense disease pressure imaginable.

Heat Tolerance

Plots at PST East are put to the test by North Carolina's scorching heat and relentless humidity. Only the most resilient varieties survive.  PST varieties thrive in tropical and subtropical climates. 


Our breeding program offers a spectrum of turfgrass colors, from rich, dark green to a stunning light blue. Find the perfect shade to complement your landscape vision.

Low Maintenance 

By selecting varieties that thrive under low fertility conditions, we are essentially breeding for efficiency. These grasses require less fertilizer, which saves you money and reduces environmental impact from excess fertilizer runoff.

Sod Quality

Sod quality with built-in performance traits gives you unmatched results where you need it most. 


In our forage program, we ensure the highest standard for palatability is met for your animals: soft leaved, digestible, nutritional, and high in sugar. 

Salt Tolerance

Our commitment to water conservation extends to brackish water irrigation. Through rigorous salt tolerance trials reaching 20,000 ppm NaCl (ocean levels average 35,000 ppm), we identify turfgrass varieties that persist in these conditions. 

Quick Establishment

Fast establishment means a thriving lawn, sooner. PST has revolutionized Kentucky bluegrass through its QuickBlue lineage that establishes at a rate similar to perennial ryegrass. 

Shade Tolerance

PST West features the world's largest privately owned trial dedicated to studying the effects of shade on turfgrass.

Cold Tolerance

For decades, we've conducted rigorous cold germination trials across multiple grass species. This translates to a powerful selection of seeds specifically chosen to thrive in cool weather conditions. 


PST stress-tests its varieties with intense traffic, drought, salt, and minimal inputs. We then analyze recovery data to ensure lasting performance. 

Seed Yield

By focusing on varieties that produce high seed yields, we can get more seeds from a smaller area of land. This leads to more sustainable agriculture and longevity of the varieties and products  we release to the market.


We meticulously screen for overseeding traits that ensure success: rapid establishment, quick recovery, seamless transition, and dark green color.


All Pure Seed forage varieties are bred with flexibility in mind - for cutting or grazing, across a wide range of soil types and climatic conditions.
