The discovery solves a two-decades-old mystery that has vexed David Huff, professor of turfgrass breeding and genetics, whose research trials at the College of Agricultural Sciences' Joseph E. Valentine Turfgrass Research Center are aimed at breeding Poa annua to produce seed for greens.
Poa annua is a remarkably versatile grass species with both perennial and annual biotypes, Huff noted. The species can be found as an invasive weed on all seven continents of the globe, including extremely inhospitable locations such as Mount Kilimanjaro and Antarctica. It is valued on greens because of its tenacious quality, persisting in closely mowed, high-trafficked conditions where the most-valued turfgrass species for putting greens, creeping bentgrass, often struggles to survive.

Cobblestone Golf Course, a municipal course in metro Atlanta owned by Cobb County and operated by Bobby Jones Links, announced the start of renovations to its practice facilities, including expanding and improving the putting green as well as providing a larger, more useful chipping green to golfers.
To assist in renovations, Cobblestone Golf Course has hired contractor Kevin Selsor of Traditions Turf to oversee construction. Traditions Turf Management will be enlarging the chipping green to over double its original size, from 1,135 square feet to over 2,800 square feet. The bunker will remain but will be smaller in size to accommodate the larger chipping green. The size of the putting green will also increase, expanding from 3,925 square feet to 7,325 square feet. In addition to the expansion, the sloping of the putting green will be smoothed out to provide more puttable space overall.
“We are excited to embark on these new enhancements to the course,” Cobblestone general manager Terry Harnage said. “Kevin Selsor has always been a big fan of Cobblestone Golf Course, and we are lucky to have Traditions Turf working with us on this project.”
Work on the course began in mid-April and will conclude by the first week of June when the grow-in process is complete. Upon completion, the course will provide a larger, flatter practice putting surface that will be easier to maintain and will make for a better practice experience for players. There will also be two areas for golfers to practice putting, which will be much more functional for camps, lessons and golfers who prefer to remain at the practice facility.
Cobblestone Golf Course, a Ken Dye design with Champion Bermudgrass greens, opened in 1993 and underwent a full renovation in 2010.
