Ann Clary

Ann Clary


Ann Clary met her GardenZeus.com co-founder Darren Butler at one of his intermediate gardening classes and she became inspired to grow new and different plants in a sustainable, bio intensive manner.  After finding herself constantly creating monthly to-do lists for California gardening from four or five different resources, she thought there had to be a better way.  This became the original impetus for Ann and Darren’s partnership, the process that evolved into GardenZeus.com.

Ann is a professional lawyer and administrator, and an avid amateur gardener. She lives in Pasadena, California and she enjoys cooking for her husband and two grown children. She especially likes to cook what she grows in her vegetable garden. Ann is a big fan of Alice Waters, Julia Child, Thomas Keller and Nora Ephron. She says, “I know Nora was not really a professional cook, but she liked to cook and had lots of funny things to say.” Ann is also a competitive tennis player and an avid Stanford Cardinal football fan.

Darren Butler

Darren Butler


Darren Butler is a Consulting Arborist, Ecological Landscape Designer, Greywater & Irrigation Designer and Consultant, Landscape & Garden Consultant, Permaculturist, Speaker, and Teacher. He started gardening at age five, working summer landscaping jobs and in orchards as a pre-teen and teen, and as of 2014, has 27 years of diverse adult experience working with plants, trees, gardens, and landscapes.

Darren’s beginnings as a gardener and arborist were in a strip of trees behind the home where he grew up as a young child, the last remnant of what had been a native woods in upstate New York. He played among the trees and began climbing them by the time he was walking. When he was about five years old, his parents started a vegetable garden for the first time. He still remembers the first seeds he ever planted, snap peas, and the wonder and amazement he felt in doing so.

Over his lifetime he has gardened extensively in New York (as a child), Utah, and Southern California, with professional plant-care experience also in Northern California. In the mid-1990s, he began the long process of teaching himself how to garden in the alkaline clay soil and dry Mediterranean climate of the San Fernando Valley in Los Angeles. He became a University of California Master Gardener in 2005, and began designing landscapes, and consulting as a landscape/garden/irrigation expert and arborist that same year.

Over the years Darren has accumulated professional qualifications and accomplishments to distinguish himself and to earn a living as an independent landscape consultant, teacher, designer, and speaker. Darren has appeared on international television for a large audience, NPR radio, local television, and in many other media as an expert, and has worked as a testifying arborist expert witness. He maintains many landscape- and plant-related certifications and licenses including ISA Certified Arborist, University of California Master Gardener, Certified Landscape Irrigation Auditor, Permaculture Design Certificate, and ISA Certified Tree Risk Assessor.

He has been a frequent presenter at conferences and symposia, and been keynote, plenary, featured, or main-stage speaker at many major events, including 2010 through 2012 California Homeschool Network Annual Conference and Expo, 2011 Southern California Permaculture Convergence, 2010 Huntington Botanic Garden Symposium on Urban Agriculture, 2009 City of Riverside’s Earth Day Festival put on by Habitat for Humanity, and 2009 Long Beach Green Festival, and has been a speaker at dozens of major conferences and events, including the 2008 and 2011 California Statewide Master Gardener Conferences, and the 2010 American Horticultural Society’s Youth and Children Gardening Symposium.

Since 2005 Darren has offered dozens of workshops, courses, presentations, and retreats to thousands of students and attendees on topics related to gardening, landscape design and management, urban agriculture, trees, irrigation, permaculture, sustainability, horticulture, and more. He has guest-taught or presented in a wide variety of venues such as botanic gardens, university and professional symposia, festivals, water district offices, churches, and community centers.

Darren has taught Designing Sustainable Landscapes and Diagnosing Plant and Tree Problems for the UCCE LA County Master Gardener Training Program for eight years, and volunteered as a University of California Master Gardener since 2005. From 2007 to 2009 he served on statewide Advisory and Steering Committees for all University of California Master Gardener programs through the statewide MG offices at UC Davis, which influenced the outreach efforts of thousands of California Master Gardeners and more than 100,000 California residents they serve every year.

From 2011 to 2013 he taught two runs of a major, 48-hour train-the-trainer course at the Huntington Botanic Garden on cutting-edge urban agricultural methods called “Urban Ecosystem Agriculture.” From 2010 to 2013, he worked as garden manager and teacher for an at-risk kids’ gardening program at A Place Called Home in South Los Angeles. In 2010 he blogged at KPCC radio’s Facebook community, The Freeway. In 2008 he was a core teacher for a permaculture design course (PDC) with Graham Burnett, Scott Horton, and William Faith. In 2007 and 2008 he developed curriculum for and taught certification programs in Sustainable Biointensive Gardening and Edible Landscaping. Since 2008 he has offered mentorship and apprenticeship programs in arboriculture, landscape design, and other topics to many adult apprentices.

Darren has worked as a consultant and designer for a variety of clients from celebrities to nonprofit organizations to everyday citizens, and since 2005 volunteered thousands of hours primarily to educate, promote sustainable practices, support programs that help people grow and eat nutritious food, serve at-risk children and youth, and to serve others in discovering meaningful and joyful experience through connections with plants, trees, soil, and gardens.
