above Glen Ellen, CA. In 1968, San Francisco resident Jane Davenport Jansen purchased forty-plus acres northeast of Glen Ellen, CA for a summer home. In 1970 she planted cabernet vineyards on the valley floor of the property. In 1982, Jane began to consider the uncultivated parts of the property inspired by a partnership with Roger Warner. After a flood around Jane's house in 1982, Jane was introduced to Roger who redesigned the landscape reminiscent of an English garden with a selection of California native plants and rarities from China. In 1985, a landscape partnership between Jane and Roger was formed and plans for a 25-acre hillside botanical garden began. In 1987, Jane sponsored the first collecting expedition to Asia. In that year, the relationship between her and Roger Warner suddenly dissolved and Lord Howick of the Howick Arboretum helped Jane refocus her vision for the garden. They planned for a conservation of rare and endangered Asian species. In 1988, cooperative expeditions with the Royal Botanical Gardens, Kew Gardens, and the Howick Arboretum began. The property was named Quarryhill Botanical Garden and a small nursery was established to cultivate the wild-collected seeds. Planting began in 1990. Preserving these threatened species and celebrating biodiversity was the foundation for the garden's mission. Jansen appointed William A. McNamara Director in 1994 and he became Executive Director in 2007. In 1998, an additional 22-acres, Three Springs Ranch, was purchased. In 2000, Jane died suddenly at the age of 60. In 2002, the garden opened to the general public (previously open only to private tours). In 2003, the garden developed a multi-institutional online database (DAPC) to share information about the rare and endangered Asian plants both at the garden and in the larger botanical community. In 2017, the Nuns fire burned three sides of adjacent property to the garden. Aside from a few scorched fenceposts and lost vines, the garden was unscathed. In 2021, Quarryhill Botanical Garden became Sonoma Botanical Garden and expanded its mission to include California native plants.

Seed-collecting expeditions
