Southern Blue
A Texas Bluegrass Hybrid
This innovative cool season cross between a Texas bluegrass and Kentucky bluegrass was developed through a partnership with Texas A&M and NG Turf. Southern Blue out performs all other cool season grasses during Southeastern summers while remaining cold hardy and keeping its deep green color year round. The rhizomatous root system not only provides heat and drought resistance, but also allows the grass to recover from stress and damage—unlike fescue, which requires overseeding.
