NEW CLASSES coming & our Ethnobotany Festival in 2018

by Botanical Dimensions on 11/21/2017

We have some great learning opportunities coming up in 2018. Kathleen Harrison and guest teachers will offer all-day and half-day classes on a variety of topics, beginning in March.

  • 4-part Global Ethnobotany with a Local Focus, taught by Kathleen Harrison over 4 months, with nature walks.
  • The Art of Seeing, Drawing & Painting Plants: a weekend with artist Donna Torres and Kathleen Harrison
  • Who is Tobacco? An all-day workshop that examines a variety of spiritual and protective uses of this complex plant teacher. With seeds and samples for cultivating your own healthy ally. (This plant is not all shadow.)
  • Plants and Cultures of the Motherpeace Tarot, taught by this classic deck’s co-creator and artist, Karen Vogel.
  • Sweeping the Mountain of Nerves – Universal techniques in cleansing, grounding and protecting yourself or others, with Kathleen.

Our biennial Ethnobotany Festival & Symposium will happen again next harvest season. The first one was spectacular, so be sure to not miss the next one. All ages welcome.  You’ll just have to come visit the festival, our library, and the beautiful redwood forests of West Sonoma County. Then swing by the spectacular Sonoma Coast, while you’re so near it. In September, exact date to be announced soon.

Native plants provide food and basket material, in the skilled hands of native people.



On Friday, Nov. 10, 6-8pm, at the Glaser Theater on Mendocino Ave. in Santa Rosa, CA. Please join us to hear Dr. Greg Sarris —professor, writer, Tribal Chairman of the Federated Indians of Graton Rancheria— reads from his newest book, which is dedicated to knowledge of place. This very place, Sonoma County, Northern California, is home to Botanical Dimensions and so many fine people. Indigenous people have been here for many millennia. Coast Miwok and Southern Pomo people explain the origins of features of our region with their rich stories. In this book, Sarris draws from those creation tales. BD is please to be one of the sponsors of this event. It’s free to all, no charge. Please join us to add to your appreciation of this beautiful land that has just come through massive wildfires. The land and its beings (all species) have been here for a long time, resilient. It calls upon all of us to help renew after fires, and to listen to its stories.

Saturday, April 15, from 3-6PM. At the Occidental Center for the Arts, adjacent to BD’s Ethnobotany Library. Tickets available at the door, or now at

Cannabis and Spirituality – An Explorer’s Guide to an Ancient Plant Spirit Allyis a thought-provoking new book. Editor Stephen Gray (Returning to Sacred World) and ethnobotanist Kathleen Harrison will read from their chapters in the book, and talk about spiritual, ritual or meditative relationships to this profoundly influential plant. Martin A. Lee (author of Smoke Signals: A Social History of Cannabis, and Acid Dreams) will speak as well. The authors will hold an onstage discussion with each other and audience, exploring questions about the breadth of spirituality, the many ways it may be experienced in regard to cannabis, and the many-faceted role of cannabis in these times.

Reserve your spot by purchasing your ticket online here.

Before the talks or during intermission, visit Botanical Dimensions’ adjacent Ethnobotany Library, which is filled with books about plants, cultural beliefs, herbal medicine, mushrooms, mythology and much more.
