Raised in Alaska, where the sun never rises in the winter and the trees are stunted by permafrost, Teo Spengler fell in love with plants when she moved to California for college. Gardening became more of a passion than a pastime, as she studied horticulture and took master gardening courses. Spengler completed an intensive sixteen-week program to qualify as a docent at the San Francisco Botanical Garden and has given public tours there for some years. She has also earned a BA in politics, an MA in English, an MFA in creative writing, and a JD from Berkeley Law School. She has written about nature, trees, plants, and gardening for 20 years for a variety of websites including Gardening Know How, Hunker, Home Guides, San Francisco Chronicle and Gardening Guides as well as publishing two novels, following a long career as an attorney and legal writer. Spengler currently splits her life between San Francisco and the French Basque Country where she has practiced her skills in both personal and public gardens for the past two decades. Her extended family includes some 30 houseplants and hundreds of outdoor plants, including 250 trees—mostly oaks, birches and beeches—that she planted on her land in France.
