A location-neutral summary of turf-quality performance across the NTEP sites where this cultivar was evaluated. It is not a recommendation for your location. It is PoaIndex’s summary of historical NTEP quality data — not an NTEP endorsement, and not a claim that the cultivar is nationally best.

Location-specific cultivar rankings use a different method (your ZIP). Cultivar Explorer does not score cultivars for a lawn address.
