Most popular Barenbrug product for summer sports
Barenbrug’s go-to blend of fine perennial ryegrasses, for all-purpose use in areas requiring medium-fine turf, close-mowing and high wear.
USAGE:
Designed to create the perfect, lasting surface for tees, fairways, walkways, cricket squares and outfields, and tennis courts, when overseeding, divoting and constructing. Producing a medium-fine turf for intensive wear and good tolerance of close-mowing regimes.
FEATURES & BENEFITS
All four Barenbrug-bred cultivars bring advantages and different characteristics to this product.
Barzico is an elite cultivar for medium-fine turf under wear traffic. It is ranked #3 on Table S1 and within the top third on L1 in BSPB Turfgrass Seed 2026.
Barpersie is a recent addition to EXTREME. A high performing, all-round cultivar. Ranked #9 in Table S1 and #2 in Table L1 in BSPB Turfgrass Seed 2026, this new cultivar combines exceptional wear tolerance and recovery with fineness of leaf and density; its mean score of 8.9 as a new cultivar in Table G4 is groundbreaking.
Baradona offers outstanding all-round wear tolerance, shoot density, and aesthetics. With a mean score 7.4 in Tables S1 and L1 of Turfgrass Seed 2026, it is one of the few cultivars to hold top-30 high rankings in both lists.
Barprium is an exceptional ryegrass for summer sports use. Its use in both Ultrafine and SGT products shows its versatility in turf management.
Tees, fairways, walkways, cricket squares and outfields, tennis courts and high-traffic lawns are perfect examples of where this grass seed mix is at home.
If fineness of leaf or tolerance to very close mowing are the driving factors in product selection, ULTRAFINE 100 is recommended as a possible alternative.
