Daniel Hinkley is a plantsman, author, lecturer, nurseryman, and horticultural consultant. He earned a B.S. in Horticulture and Horticulture Education from Michigan State University and an M.S. in Urban Horticulture at the University of Washington. His first garden, Heronswood, near Kingston, Washington is now owned and operated by the Port Gamble SKlallam Tribe and is open to the public throughout the year.

Dan's current garden, Windcliff, is just a few miles from Heronswood. It sits on a high bluff overlooking the Salish Sea. For forty years, Hinkley has traveled the globe to similar climates to observe and preserve plants that deserve recognition as possible new additions to landscapes worldwide.

He has written four books and has been recognized by his peers in receiving numerous awards for his work, including the Liberty Hyde Bailey award from the American Horticulture Society, the Scott Gold Medal from the Scott Arboretum, and the Veitch Memorial Medal from the Royal Horticultural Society.

Kristin Ohlson is a writer from Portland, Oregon. Her new book Sweet in Tooth and Claw: Stories of Generosity and Cooperation in the Natural World – which the Wall Street Journal calls “excellent and illuminating”--probes the mutually beneficial relationships among living things that undergird the natural world. Her last book was The Soil Will Save Us: How Scientists, Farmers and Foodies are Healing the Soil to Save the Planet, which the Los Angeles Times calls “a hopeful book and a necessary one…. a fast-paced and entertaining shot across the bow of mainstream thinking about land use.” She appeared in the award-winning documentary film, Kiss the Ground, to speak about the connection between soil health and climate health.
Ohlson’s articles have been published in the New York Times, Orion, Discover, Gourmet, Oprah, and many other print and online publications. Her magazine work has been anthologized in Best American Science Writing and Best American Food Writing.
