Reimagining Sonoma’s Spectacular Botanical Garden

with Scot Medbury, Executive Director, Sonoma Botanical Garden

Tucked against the rugged foothills of the Mayacamas Mountains in the famed Sonoma Valley, the Sonoma Botanical Garden is relaunching itself as a more relevant resource for gardeners in a wildly changing climate. The 35-year-old institution, formerly known as Quarryhill, has recently expanded its mission to embrace the cultivation and interpretation of the native flora of California, in addition to its historic focus on wild-collected Asian plants. Scot will share some of the future plans for this beautiful 67-acre property, and also talk about some of its special specimens.

Scot has been involved in the curation, cultivation, and interpretation of botanical garden collections for over 40 years. He became director of the San Francisco Botanical Garden and the Conservatory for Flowers during the time of the Conservatory’s comprehensive rehabilitation. Then appointed Brooklyn Botanic Garden’s President and CEO, he returned to California in early 2020 to become the Executive Director of Sonoma Botanical Garden.

Supporting Each Other

Plants do not recognize race, economic condition, or social class. Plants can take root in any spot where they can find sufficient sunlight and moisture. Appreciating and nurturing plants can reduce stress, provide food, and promote community.

Nurturing plants can be for everyone, everywhere. Spending time around plants—gardening, spending time in a park, hiking through trees, or playing in a meadow—is good for mental health, promoting relaxation and relief from stress and worries. There are physical benefits to sunlight, fresh air, soothing scents. 

Whether you have a full garden, some house plants, or a few herbs on your windowsill, we encourage you to take time to appreciate the surroundings, smells, and textures, along with sharing your interest with others. Share photos and web links, offer horticultural help and advice, talk to young people about gardening, growing food, and the role plants play in our world. We can help shape the future for good.
