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.

A multi-species category, Fine Fescues encompasses several species including Chewings, Hard, Sheeps, Strong Creeping Red, and Slender Red Fescues. Fine Fescues are primarily used in blends and are rarely seen as individual cultivars. When maintained for drought, Fine Fescues do best in lower maintenance scenarios with longer cut heights and less traffic. With a wide geographic range, TWCA Qualified Fine Fescues are found to varying degrees in all eight TWCA regions. Kentucky bluegrass
Kentucky Bluegrass is one of the most common and valuable turfgrasses in North America. Known for its smooth boat shaped leaves and rich dark green color; this versatile cool season turf is found throughout the cool season turf range. Perennial Ryegrass
Fast germination and aggressive growth make Perennial Ryegrass popular on playing fields and in high traffic turf applications like public parks. Found through most of the cool season turf range, Perennial Ryegrass is also used to overseed warm season turf. Tall fescues
Name
Tall Fescue is a hardy and adaptable species of cool season turf that is well known for drought tolerance. A versatile, durable turf, with good drought tolerance; Tall Fescues are found through most of the cool season turf range and provide an alternative to warm season turf in many areas. 2024 Qualifications2020 Tall Fescue trial is over, and the latest qualifications are in! Get the latest report from TWCA and learn more about new cultivars to make every drop count. Newly qualified cultivars will be added to the website listings by 15 March 2024. |

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. |
