80 % pâturin des prés / 20 % ray-grass vivace
Four Elite 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.
Jumpstart is widely regarded as the quickest-establishing elite Kentucky bluegrass available, and it's in this blend for exactly that reason. Kentucky bluegrass is slower to germinate than other cool-season species, and Jumpstart directly addresses that. It outpaced 85% of entries in NTEP establishment trials and scored in the top 13% for seedling vigor across seven test locations. It also scored 7.7 for colour at the Guelph, Ontario test site and brings strong spring green-up, meaning your lawn shows visible progress faster and greens up earlier after winter.
- Widely regarded as the fastest-establishing elite Kentucky bluegrass available. Less time waiting on bare soil
- Holds density into late fall. 99% ground cover at the Fargo, ND drought stress trial
- Good heat tolerance with quick recovery after summer stress
- Self-repairs through underground rhizomes. Fills in bare spots and wear damage over time
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. Where Jumpstart gets your lawn established quickly, Prosperity is the long-term anchor. It brings strong colour genetics, 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
- Strong leaf spot resistance. Scored 7.9 / 9.0, ranking #6 of 100+ entries
- 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
Blue Devil is a sub-compact midnight-type Kentucky bluegrass with some of the darkest colour genetics in the NTEP trial, scoring above 7.0 at four or more test sites including 8.1 at North Brunswick, NJ. It also carries the strongest disease resistance of any cultivar in this blend, with a 7.8 out of 9.0 dollar spot score. In a province where cosmetic pesticide bans mean you can't spray for disease, that matters. Blue Devil adds fine texture and high density to the blend, contributing to a tight, uniform stand.
- Among the darkest Kentucky bluegrasses tested. Scoring above 7.0 at 4+ NTEP trial sites
- Scored 7.8 / 9.0 for dollar spot resistance. Fights disease on its own
- Among the top 10 entries for wear tolerance under spring traffic stress
- Fine texture with dense, tight growth for a uniform appearance
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
