Choosing Turfgrass Summary Turfgrass choices are the species, cultivar, type of planting material, and quality, for  a specific site.   In conjunction with choosing the turfgrass, the landscape and  turfgrass manager is concerned with getting the turf to the site in healthy condition.  The lecture will contain much more specifics, so this write-up is intended to provide  a foundation. Why? The   consequences   of   turfgrass   selection   are   both   long-   and   short-term,   and  somewhat unpredictable.   Long-term consequences of turfgrass selection include  longevity, maintenance cost, and suitability of a turf to a site or use.  Short-term  consequences of turf selection are the purchase price, including any delivery or  contract installation costs, and associated costs such as consultant's fees, travel to  visit the sod farm, and inspection costs.   Hardest to estimate in turfgrass selection are risk factors, that is, the variability of,  performance and quality.   A grass that does well on one site may do poorly at  another,   due   to   factors   that   were   not   known   or   not   sufficiently   understood  previously.   Although plantings at both sites cost the same initially, the failed  planting may cost two or more times as much as the successful planting.   A turfgrass species such as bahiagrass,  Paspalum notatum , may be poorly adapted  to   a   site   because   it   requires   more   illumination   (i.e.,   "photosynthetically   active  radiation") than the site provides, due to tree shade.   Such a planting in South  Florida fails typically within two years, as the bahiagrass thins and becomes infested  with weeds.   Hybrid bermudagrass,  Cynodon  sp., is sometimes planted as an accent for high-end  properties such as homes for the wealthy.  Such an application serves to provide a  visual distinction from neighboring properties, but often the maintenance costs is  out of proportion to the benefit, for that use.   Knowing how to choose a turfgrass enables the landscape and turfgrass manager to  make appropriate decisions for the client or employer.  Species and cultivars There are hundreds of turfgrass cultivars available.  Few are suited to a particular  use.   In Florida a vegetatively propagated clone, 'Floratam' St. Augustinegrass,
