This data publication includes raster digital files containing plant hardiness zones of current climate (1981–2010) and future climates (2070–2099; CanESM2, GFDL-ESM2G, and HadGEM2-ES general circulation models at representative concentration pathway 8.5) in the conterminous United States. Plant hardiness zones represent the coldest day of the year, averaged over 30 years. For the plant hardiness zones, we identified the lowest daily minimum temperature of the winter-centric year (July–June) and then averaged each year’s extreme daily minimum during 30 years. We assigned 5.6 °Celsius (°C) zones and 2.8 °C half zones. Visualization of plant hardiness zones of current climate (1981–2010) and future climates (2070–2099) in the United States. Original metadata date was 08/09/2019. Minor metadata updates were made on 08/21/2019.
