Western Natives
Plants that are adapted to the west can handle our capricious weather, dry summers, and differing soil conditions. Native plants should always be included in our gardens. Many are
losing their native ranges to development and foreign invasive plants. Our list includes not only plants from political
borders but from the far west that are adapted to our gardens.
Oregon native plants are in green.
