There are a number of potential advantages to using bluegrass hybrids for lawn and sports turf applications in Colorado.
It possesses excellent heat tolerance and, in fact, seems to grow better the warmer it gets in the summer. These hybrids produce an extensive root system, which enhances heat and drought resistance. This grass forms large, extensive and aggressive rhizomes (underground stems). Grasses that produce rhizomes are better able to tolerate traffic and will recover more quickly from traffic-induced wear. There is a good amount of anecdotal field evidence that these hybrid bluegrasses require less supplemental irrigation than some of the Kentucky bluegrasses.
