No Weeds | No Filler | Elite Quality

100% Elite Perennial Ryegrass

Perennial ryegrass is the fastest-germinating cool-season grass — it can be up and growing in under a week. It's known for its fine texture, dark colour, and the clean, reflective shine it gives a freshly mowed lawn. It tolerates low mowing, handles foot traffic well, and is the go-to species for overseeding an existing lawn.

But not all perennial ryegrass is the same. Within the species, there are individual varieties called cultivars — each bred for different strengths like disease resistance, colour, density, or stress tolerance. The cultivars in big-box seed bags are rarely identified and are almost never trial-tested. Ours are.

This blend combines three elite cultivars in equal parts — Alpha Centauri, Principal II, and Process — each hand-selected from recent National Turfgrass Evaluation Program (NTEP) trials. Alpha Centauri brings dark colour and early spring green-up. Principal II brings consistent all-round quality across every region it was tested in. Process brings one of the strongest disease resistance packages in the trial. Blending all three gives your lawn the combined strengths of each, which means more resilience, broader disease resistance, and better performance across a wider range of conditions.

This has been one of our most popular products since we launched. Thousands of Canadian homeowners have seeded it with outstanding results. Blue Tag certified. 0.00% weed content.

Performance Data — NTEP Scores

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
Elite Perennial Ryegrass

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
Elite Perennial Ryegrass

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
Elite Perennial Ryegrass

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
