There's some new bluegrass on the market, a cross between Kentucky Bluegrass and Texas Bluegrass. Lesco's is called Longhorn Hybrid, and Scotts is called Thermal Blue. From what I hear, you get all the benefits of bluegrass and supposedly are MORE resistant to heat, drought, and disease than TTTF. They sound very good, but are expensive. Anyone try it yet, or plan on trying it out?
