Rhizomatous Tall Fescue (RTF) or Perennial Ryegrass
RTF is a species of turf grass that is extremely durable and dense. It creates rhizomes, which are underground stems that grow laterally through the soil to stabilize and spread the turf grass. These rhizomes stem upward to the surface while also growing new roots downward, creating new plants. The process is pretty similar to that of the Kentucky Bluegrass. However, RTF differentiates itself with the ability to survive the transition zone climate and additional tall fescue turf regions.
Perennial Ryegrass varieties first come through intensive breeding programs and then prove themselves at the highest levels in the National Turfgrass Evluation Program. Each performs well in our Northwest climate and under all levels of management including the gold course, commercial or residential landscapes. The current three-way blend of perennial ryegrass is (Blue Tag Certified): 33.3% Home Run perennial ryegrass, 33.3% Apple GL perennial ryegrass, and 33.3% Stellar GL Perennial ryegrass.
