3 Dark Green Cultivars, One Custom Blend
For Canadian Lawns: Versatility and Unmatched Dark Green Colour
Three Cultivars. The Data Behind Each One.
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
Prosperity is an elite Kentucky bluegrass with one of the longest performance records of any cultivar we carry, tested across three NTEP trial generations spanning nearly 20 years. Its defining trait is colour: Prosperity has finished in the top 5 for genetic colour in every trial it has entered, including a score of 7.7 at the Guelph, Ontario test site. But what makes it essential to this blend is what only a Kentucky bluegrass can do. Prosperity spreads underground via rhizomes, meaning it actively fills in thin spots, pet damage, and wear over time. Something neither ryegrass nor fescue can offer. It also brings strong leaf spot and dollar spot resistance and handles drought better than most bluegrasses in the field.
- Consistently among the darkest Kentucky bluegrasses tested. Top 5 for colour across three NTEP trials
- Establishes faster than most Kentucky bluegrasses. Top 20% for seedling vigor
- Self-repairs through underground rhizomes. Fills in bare spots and wear damage over time
- Above-average drought tolerance for a Kentucky bluegrass. Ranked #3 of 100+ entries
- Tolerates low mowing heights. Bred for close cutting down to 0.5"
Kevin is a strong creeping red fescue and the cultivar in this blend designed for the areas of your lawn where Kentucky bluegrass and perennial ryegrass can start to thin out. Fine fescues are the most shade-tolerant cool-season grasses available, and Kevin brings that tolerance along with a fine leaf texture that blends cleanly with the other species in the mix. It also spreads via rhizomes, helping it fill in and persist in lower-light areas over time. Among the 43 fineleaf fescue entries in the current NTEP trial, Kevin ranks in the top 25% for genetic colour, including a score of 7.7 at the Quebec, Canada test site. It won't look washed out next to the darker cultivars in this blend.
- Top 25% for colour among all fineleaf fescues tested. Won't clash with the darker cultivars in this blend
- Thrives in partial shade where bluegrass and ryegrass can start to thin out
- Fine leaf texture. Blends visually with KBG and PRG for a uniform look
- Spreads via rhizomes to fill in and hold ground in shaded areas
- Persists with less water and less fertilizer than the other species in this blend
All of our elite grass seed blends are tested for purity, contain 0.0% weed and crop seed, and are built from high-performance cultivars with top NTEP ratings — the same types of seed trusted by turf professionals across Canada.
