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 several 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 more than two decades for publications including Gardening Know How, Hunker, Home Guides, the San Francisco Chronicle and Gardening Guides, as well as publishing two novels. Before focusing on gardening, Spengler had a long career as an attorney and legal writer – experience she now also brings to her role as Gardening Know How’s Gardening Lawyer.
Spengler currently splits her life between San Francisco and the French Basque Country, where she has practised 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.
