Mélange de graines de gazon Elite Shade
Five 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.
Hype 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 Hype scored 7.0 out of 9.0 in the NTEP shade trial at Ames, Iowa, finishing third among all strong creeping red fescue entries. It also ranked first in its species group for drought tolerance and scored 7.0 for colour at the Quebec, Canada test site. Along with shade performance and colour, Hype brings a fine leaf texture that blends cleanly with the other species in the mix, and it spreads via rhizomes to fill in and persist in lower-light areas over time.
- Scored 7.0 / 9.0 in the NTEP shade trial. Thrives where bluegrass and ryegrass can start to thin out
- Top 15% for colour among all fineleaf fescues tested. Won't clash with the darker cultivars in this blend
- Most drought-tolerant strong creeping red fescue in the trial. Handles dry conditions with less water
- 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
Shadow III is a Chewings fescue and the cultivar in this blend built for the conditions that shade creates. Shaded areas stay damp longer, dry slower, and give fungal diseases more opportunity to take hold. Shadow III scored 8.0 out of 9.0 for brown patch resistance and 7.0 for dollar spot in the NTEP trial, backed by high endophyte levels that contribute to its natural disease resistance. As a Chewings fescue, it brings a dense, upright growth habit with fine leaf texture that blends cleanly with the other species in the mix, and it requires less water and less fertilizer than the ryegrass and bluegrass in this blend.
- Fights brown patch and dollar spot on its own. Both diseases thrive in the damp, low-airflow conditions shade creates
- Dense, upright growth habit. Forms a tight turf without spreading into adjacent areas
- Persists with less water and less fertilizer than the other species in this blend
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
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
Blue Devil is a sub-compact Kentucky bluegrass and the only cultivar in this blend that spreads underground via rhizomes. In a shaded lawn, thin spots from foot traffic, pet damage, or seasonal stress don't fill in on their own unless something in the mix can actively spread. That's the job Blue Devil does. It also brings dark genetic colour, scoring above 7.0 at four or more NTEP trial sites including 8.1 at North Brunswick, NJ, and strong dollar spot resistance in the damp conditions shade creates.
- The only cultivar in this blend that self-repairs. Spreads via underground rhizomes to fill in thin spots over time
- Dark genetic colour confirmed at multiple NTEP trial sites. Won't wash out in lower light
- Scored 7.8 / 9.0 for dollar spot resistance. Fights disease in damp conditions without intervention
