"A 67-acre garden just north of Glen Ellen focused on conserving endangered wild plants—especially rare Asian trees—and recently expanding its collection to include California natives. Depending on season you may encounter flowering trees and shrubs such as magnolias, camellias, and rhododendrons; visitors can explore gently hilly trails with a map or join docent-led tours, and there is a gift shop geared to gardeners. Open daily year-round except Tuesdays from 9 a.m. to 4 p.m.; adult admission is $12." - Pat Tompkins
