100 % ray-grass vivace Elite
Three PRG Cultivars. All NTEP Tested.
Every cultivar in this blend has been through the National Turfgrass Evaluation Program (NTEP) — a multi-year, multi-location trial run across universities and research stations. Cultivars are evaluated blind and scored on quality, colour, density, disease resistance, and stress tolerance under real-world conditions.
NTEP uses a 1-to-9 scale, but scores above 7.0 are rare in practice. A 6.0 is considered acceptable. Anything above 7.0 puts a cultivar near the top of the field.
Here's how each one performed.
Alpha Centauri is a new elite cultivar we introduced in 2025 — and the centrepiece of this blend. It offers dark green colour with individual NTEP site scores as high as 8.0, but what makes it rare is what comes with that colour: strong disease resistance, early spring green-up, and excellent salt tolerance. Most of the darkest-scoring ryegrasses in the NTEP trial gave back performance in other areas. Alpha Centauri didn't.
- Dark genetic colour — scoring up to 8.0 at individual trial sites
- Fast seedling vigour — establishes quickly and fills in dense
- Fights dollar spot on its own — critical in provinces with cosmetic pesticide bans
- One of the first cultivars to green up in spring
- Excellent salt tolerance for Canadian winters
Principal II is a new generation of perennial ryegrass released in 2018 — an advanced poly cross bred from plots in both Oregon and New Jersey. Its defining trait is consistency: it finished in the top 5 of 112 entries for overall turf quality across 23 locations over five years, performing well in every region rather than excelling in one and falling off in another. It also brings one of the strongest gray leaf spot resistance scores in the trial and recovers from damage faster than most entries tested.
- Performs well across a wide range of climates and conditions
- Strong natural disease resistance — handles gray leaf spot without chemicals
- Recovers from foot traffic, pets, and wear quickly
- Fills in dense with good seedling vigour
- Tolerates salt and cold stress through Canadian winters
Process is a modern cultivar bred with one of the strongest disease resistance packages in the 2016 NTEP trial. It scored 8.3 out of 9.0 for gray leaf spot resistance and 7.5 for brown patch — both near the top of 112 entries. In provinces where cosmetic pesticide bans mean you can't spray your way out of a disease problem, cultivars that fight it on their own matter. Process also brings dark genetic colour and excellent wear tolerance, making it a strong anchor in any blend.
- One of the strongest gray leaf spot resistance scores in the trial
- Handles brown patch naturally — no chemical intervention needed
- Dark colour with fine texture for a clean, uniform look
- Excellent wear tolerance — built for traffic and recovery
- Cold tolerant and quick to establish
