Narrative
Coarse-textured, vegetatively propagated clone noted specifically for tolerance to drought conditions and low water use, excellent cold hardiness, and rapid recuperative ability. Intermediate in salt tolerance. Agressive recovery growth from rhizomes and stolons, medium-coarse texture, good winter hardiness, good to excellent shade tolerance, and low water use requirement. Highly competitive to weed invasion under low management conditions. Harvest cycle can approach 8-12 months, in contrast to the industry standard Meyer that averages 15-24 months. Uniform in growth expression, genetically stable (2n=40), flowers prolifically, but has low self-fertility. Adapted to the Southern U.S. northward to central Kansas, based on National Turfgrass Evaluation Program trials conducted from 1991 through 1994. Suitable for use on golf coarse roughs, as well as home lawns, sports fields, industrial parks, and highway rights-of-way. Adapted to moderately shaded to full sun turf areas, and in areas where water quality and quanity is a problem. Optimum mowing height will range from 5.0 to 7.5 cm.
