  • 1995: Sunset refined and expanded the climate zone maps, setting gardeners up for greater success despite the growing demands on their time.
  • 2001: Sunset introduced “natural-sustainable” gardening, well before the idea went mainstream;  the encyclopedia was expanded to include 2,000 plants.
