WSU's Native Plant Guide [posted on August 8, 2006]
Native plants are plants that occur naturally in your region. The plants native to your region have grown alongside the native insects, fungi, plant diseases, wildlife, and other native plants for thousands of years. In addition, the plants native to your area are adapted to growing in your region's soils and climate, and so generally require less maintenance (such as watering) than do non-natives. This site provides an easy to use database that can help you identify and care for these plants. [Native Plant Guide]
