No Weeds | No Filler | Certified Elite Grass Seed

Introducing Alpha Centauri

Certified, Best-in-Class Elite Perennial Ryegrass

Alpha Centauri is a new elite perennial ryegrass cultivar that is available for the first time in 2025. We think Canadian lawn enthusiasts are going to love it and are excited to be able to offer it as a dedicated option in both our 2kg and 5kg bag sizes. Each bag contains 100% Alpha Centauri perennial ryegrass with 0.00% weed and other crop seeds.

Proven and Tested for Outstanding Overall Performance, Dark Colour, Spring Green-up, and Fast Germination

Alpha Centauri offers the latest in seed breeding technology, with superior genetics that have led to impressive rankings in the National Turfgrass Evaluation Program (NTEP)—the Oregon-based research program that tests, scores, and ranks certified elite grass seed cultivars and is widely accepted as the standard for turfgrass evaluation in the U.S.A. and Canada.

Most notably Alpha Centauri scored 2nd (🤯) in overall turf performance in the latest (2023) NTEP report, with high marks in specific categories like disease resistance, spring green-up, and (dark) color.

Testing has also shown that it is durable and can handle wear, heat stress, and drought. And best of all it has excellent seeding vigor and establishment which is a fancy way of saying it can provide a quick, lush, high-performing lawn under a variety of conditions.

If you’re looking to transform an ugly lawn this year or want to take a “nice” lawn to the next level, Alpha Centauri offers best-in-class genetics and performance that could make your lawn the talk of the neighborhood.

Elite, Certified Seed vs Common Seed

Elite grass seed benefits
✅ Superior Genetics: Bred for specific traits like disease resistance, drought tolerance, improved color, finer texture, and increased wear tolerance.
✅ Certified, Higher Purity: Tested and certified to ensure it contains a very high percentage of pure seed with minimal weed seeds or other crop seeds, leading to a more uniform lawn.
✅ Improved Germination Rates: Elite seeds have higher germination rates, meaning more seeds will sprout successfully.
✅ Increased Density: Results in a thicker, more lush lawn due to the superior genetics and purity.
✅ Better Performance: Exhibits better performance in terms of overall health, appearance, and resilience.
Common (Big-Box) Seed
✖︎ One-size-fits-all blends: Always contains some mix of ryegrass, bluegrass, and fescue offering less control and potentially leading to a less uniform appearance.
✖︎ Lower Purity: Typically contains a lower percentage of pure seed and a higher percentage of "filler" and weed seeds or other crop seeds.
✖︎ Variable Germination Rates: Germination rates can vary due to lower quality of seed.
✖︎ Lower Density: May result in a thinner lawn compared to elite seed.
✖︎ More Maintenance: May require more effort to maintain a healthy and attractive lawn due to potential weed issues and varying growth habits.
