Developed by Leading Turf Scientists at Oklahoma State University

Tahoma 31™ Bermudagrass is among the most winter-hardy of the improved hybrid bermudagrasses on the market today.

Developed by top turfgrass researchers at Oklahoma State University (as OCK 1131) and, through nationwide testing in the National Turfgrass Evaluation Program (NTEP), Tahoma 31 demonstrated its resilience and excelled in key metrics compared to other bermudagrasses including Tifway, TifTuf and Latitude 36.

Tahoma 31 derives its name from the Native American word, Tahoma, which means frozen water.In test after test, Tahoma 31 shows its exceptional winter hardiness, tested up to 75% more cold tolerant than other bermudagrass varieties. With the additional characteristics of both improved wear tolerance and drought resistance, Tahoma 31 is ideal for sports turf, golf courses and high-quality lawns in the Mid-Atlantic & Transition Zone.

Tahoma 31 Bermudagrass: FAST FACTS

Tahoma 31 was rated with the lowest winterkill rate (4%) when tested in West Lafayette, Indiana, while some of its competitors.

Tahoma 31 showed superior drought resistance to four cultivars and on average, Tahoma 31 used 18% less water than TifTuf.

With little damage done in the winter, Tahoma 31 had statistically higher spring green-up ratings than competitors. 

Tahoma 31 had an establishment rate quicker than other bermudagrasses including TifTuf and Tifway

Tahoma 31 was tested in 19 locations across the United States and ranked in the top 25% of all trial entries, which indicates it is highly adaptable to different climates and soils.

Among 10 experimental grasses and one older cultivar (Tifway) tested, Tahoma 31 was ranked #1 when tested for salinity response.


Tahoma 31 Bermudagrass has the strength of the Oklahoma State University turfgrass breeding program behind it, supported by independent testing conducted by the National Turfgrass Evaluation Program.


(Varietal Name OKC 1131)


Tahoma 31 Bermudagrass, ‘OKC 1131’ was DEV in 2007 and tested in multiple years in the National Turfgrass Evaluation Program (NTEP). The NTEP National Bermudagrass Test provided data from 17 locations in 2013 and 2014, and from 19 location in 2015.

NTEP Tables

Tahoma 31 advanced to the 2013-2018 National Turfgrass Evaluation Program (NTEP) National Bermudagrass Test and excels in key metrics against other bermudagrasses such as Tifway, TifTuf, Patriot, Latitude 36 and Celebration. View the NTEP results here: NTEP tables
