Why TWCA?

Dr. Melodee Fraser, Director of Research at Pure Seed Testing East and TWCA Cooperator perfectly sums up how TWCA validates drought tolerance in turfgrass cultivars through independent third-party peer review. 
Green up your conservation program with TWCA Qualified drought tolerant turfgrass.
Special thanks to Pure Seed, Pure Seed Testing and Dr Fraser for supporting TWCA and sharing footage of their Field Day.

Our Story

​Founded in 2010 by direct competitors in the turfgrass industry, the Turfgrass Water Conservation Alliance (TWCA) is a 501 c(3) non-profit committed to water conservation and dedicated to preserving the ecological benefits of turfgrass in the managed environment.
Our approach to conservation relies on the 3rd party peer review of objective data to qualify only those turfgrasses that demonstrate a statistically significant water saving potential over conventional varieties of the same species.  By testing with research collaborators in locations across North America, the TWCA eliminates confounding factors such as soil type, heat, and pest management from the results.
