West Coasters may also want to look at Sunset Western Garden, the much-anticipated Mac and Windows title from the publishers of Sunset’s popular Western Garden book. Type in your ZIP code, and the program delivers a regional photo, along with text on weather patterns, soil conditions and some of the 6,000 plants in its database best suited to your area.
