Qualified Cultivars

Single species evaluation makes for meaningful comparisons. Comparing water use within a species allows turf managers, homeowners, and governments to use the most drought tolerant turfgrass available for a specific application. While some species thrive in a trafficked area with full sun (Perennial ryegrass and Kentucky bluegrass are excellent examples) others (fine fescues) would almost certainly die quickly in such environments. Use the tools below to find the right turf to make every drop count.

TWCA Qualification

TWCA uses peer review of objective data collected through multi-year, multi-site trialing to qualify the most drought tolerant cultivars of each turfgrass species.  
Qualification in TWCA is time limited and progressive; meaning each cultivar must either re-qualify against a new, higher standard of drought tolerance or lose its use of the seal.
Qualified products must contain a minimum of 70% TWCA Qualified cultivars.
