We've developed our own hardiness zone map that reduces the 11 zones of the USDA Plant Hardiness Zone Map into 5 zones representing turfgrasses hardiness. Why would we do this? Because turfgrasses are generally adaptable to broader ranges of temperatures than flowers, shrubs, and trees, so we widened the zones to make it easier to communicate about turfgrasses.
