Developed by Oklahoma State University Tahoma 31® Bermudagrass is among the most winter-hardy of the improved hybrid bermudagrasses on the market today! Developed by Oklahoma State University (as OKC 1131) in response to a growing demand for the next generation of winter-hardy varieties, Tahoma 31 derives its name from the Native American word, Tahoma, which means frozen water. With the additional characteristics of both improved wear tolerance and drought resistance, Tahoma 31 is ideally suited for sport turf, golf courses and high-quality lawns in the Mid-Atlantic & Transition Zone. Through nationwide testing in NTEP, Tahoma 31 excels in key metrics compared to other bermudagrasses including Tifway, TifTuf and Latitude 36.
