Garden Valley Ranch
What began as a cattle ranch in the 1880's is now home to more than 10,000 rose bushes and a renovated cottage (the original was damaged in a fire in the 1980's). Just north of San Francisco, Garden Valley Ranch is one of the few places in the country that sells chemical-free, cut garden roses, meaning they are grown outdoors without cover. Self-guided tours of the field and other gardens cost a nominal fee, and are shown by appointment only. There is also a retail nursery, which carries bare-root and potted roses in 400-plus varieties, as well as fertilizers, soil, and literature.
