In this episode, In Defense of Plants is going back in time a bit to my visit to San Francisco. What you are about to hear is a tour of Tilden Park's wonderful botanical garden whose purpose is the collection, growth, display, and preservation of the native plants of California. This was easily one of the most impressive living collections I have ever seen. The tour was led by none other than Bart O'Brien, who has been placed in charge of this amazing place. If you head on over to www.indefenseofplants.com/podcast you can find the photo album that accompanies this trip. This episode was produced in part by Mark, Allen, Desiree, Sienna & Garth, Laura, Margie, Troy, Sara, Jennifer, Christopher, Manuel, Daniel, John, Rosanna, Mary Jane, Amy, and Caitlin.
