In This Podcast: In this episode, returning guest and 50-year organic agriculture veteran Scott Murray shares the remarkable story of how coffee is commercially being successfully grown in Southern California. Scott explains how a single houseplant sparked a multi-variety coffee trial, eventually producing a Geisha harvest that sold out in one day at $796 per pound. He walks us through polyculture design, coffee’s surprising climate tolerance, and how California could become a boutique coffee region.

Our Guest: Scott Murray has over 50 years of experience in organic agriculture across the U.S. and Mexico and has served as a California conservation official for 33 years. He specializes in farm creation, farmland preservation, and regenerative polyculture systems. Scott now leads pioneering research and consulting on California-grown coffee, managing multi-variety trials and agroforestry-based plantations.

Scott Murray is a farmer, consultant, and conservation leader with 50 years of organic agriculture experience in the U.S. and Mexico. He has been a California conservation official for 33 years and specializes in farmland preservation, smart-growth planning, and farm creation. He has recently become a pioneer in growing coffee in Southern California.

Yes! Scott and his collaborators have successfully grown multiple varieties of coffee in Southern California. Their first commercial harvest in 2018 sold out in one day at $796 per pound.

It started as a houseplant experiment when Scott’s son Sam bought a coffee plant from a nursery. When it produced cherries, it sparked curiosity. Later, Scott interplanted coffee into a rejuvenated avocado orchard, creating a thriving polyculture system.

Coffee thrives with protection, partial shade, and companion plants. Avocado trees provide a microclimate that buffers wind, sun, and temperature swings. This intercropping also enhances biodiversity and farm resilience.

• Monoculture: Growing only one crop (e.g., avocados alone).
• Polyculture: Multiple crops grown together (e.g., avocados + coffee + bananas).
• Polycultures support pollinators, beneficial insects, soil health, and long-term productivity.

Scott developed a “coffee protection structure” using:

• A gopher basket
• A chicken-wire cage
• Agricultural shade fabric

This boosts early survival and results in fast, healthy establishment.

Scott is currently trialing 48+ varieties, including rare and exotic types such as Geisha and Whoosh Whoosh.

Geisha is one of the highest-value coffees in the world, known for its floral, tea-like flavor profile. Scott’s California-grown Geisha fetched $796/lb—demonstrating the potential for a specialty coffee industry in California.

Because California coffee cherries often stay on the plant for up to 12 months, the beans can accumulate more complex flavor compounds, potentially elevating specialty coffee quality.

In this garden chat, Greg and Don Titmus dive into permaculture's eighth principle, 'Information and Imagination Intensive,' highlighting its emphasis on multi-disciplinary approaches to problem-solving using both low and high-tech solutions. They delve into the importance of utilizing quality thought and data to maximize yields and share personal experiences about integrating various systems like passive solar heating, water filtration, and composting. The discussion also covers the concept of food forests, zone planning, and sustainable design strategies for reducing energy and resource consumption. They encourage community collaboration and innovation, reflecting on their own permaculture journeys and offering insights on creating self-sustaining environments. Upcoming events like the Phoenix Permaculture Design Course and the Great American Seed Up are also mentioned.

Our Guest: Don grew up in London and at age 16 spent 4 years being trained in horticulture through an apprenticeship and a college course. From there he continued landscaping in his hometown until he moved to Arizona in 1981, where he worked in landscaping and then starting his own business in garden maintenance. In 2003 he attended a Permaculture Design Course, which was life-changing for Don. He knew right away that this was the path he’d been waiting for, and later attended two Permaculture Teacher Trainings.

A Seed Chat with Bill McDorman

Register for our monthly Seed Chat at SeedChat.org

In This Podcast: In this Seed Chat episode, Greg Peterson and Bill McDorman unpack how a handful of global corporations came to control most of the world’s commercial seed supply—and what that means for biodiversity, farmers, and local food systems. Bill traces the history from small regional seed companies to mergers, patents, and Supreme Court decisions that turned living seeds into corporate assets. They also spotlight the grassroots resistance: seed libraries, landrace and adaptation gardening, community seed sharing, and regional networks working to “liberate diversity.” Listeners walk away with both a clear understanding of the problem and very practical ways to grow, save, and share seeds as an act of food freedom.

• Seed sovereignty and community control of seed
• Corporate consolidation and mergers in the seed industry
• Loss of agricultural biodiversity and its consequences
• Capitalism and the “free market” meeting biology
• Patents, intellectual property, and the Diamond v. Chakrabarty decision
• Chemical companies and private equity in global agriculture
• European common catalog and whitelist/blacklist dynamics
• Seed libraries and local seed-sharing networks
• Landrace gardening and adaptation gardening (Joseph Lofthouse)
• Going to Seed, Seed Library Network, ETC Group, Let’s Liberate Diversity
• Great American Seed Up and Seed Up in a Box as local seed strategies
• Local food economies, resilience, and community wealth

• How did we get from thousands of small regional seed companies to just a few corporations controlling most commercial seed?
• The episode traces a decades-long process of mergers, acquisitions, and the pursuit of patentable seed “assets” that could be put on corporate balance sheets, turning diversity built over 10,000 years into a narrow set of owned varieties.
• Why does the intersection of free-market capitalism and biology create such problems for seeds and farmers?
• Bill explains that when profit-maximizing logic is applied to living systems, everything that doesn’t immediately generate revenue—like locally adapted varieties and genetic diversity—gets discarded, even though it’s what makes agriculture resilient.
• What role did patents and legal decisions like Diamond v. Chakrabarty play in this consolidation?
• Once the Supreme Court allowed life forms “invented by humans” to be patented, seeds could be owned like machinery. That shift unlocked new financing for takeovers and accelerated consolidation, often at the expense of traditional, community-developed seed diversity.
• How are people and communities around the world pushing back and rebuilding seed sovereignty?
• The conversation highlights European and global movements like Let’s Liberate Diversity, ETC Group, and numerous nonprofits and seed networks that are preserving and sharing open-pollinated, locally adapted seeds outside of corporate control.
• What can individual gardeners and local groups actually do that makes a real difference?
• Listeners are encouraged to grow and save their own seeds, increase diversity in their gardens, participate in or start seed libraries, and plug into grassroots projects and classes that teach adaptation gardening and community-level seed work.

• At 00:04 — Greg and Bill introduce the theme of seed sovereignty in an age where a small number of corporations dominate the global seed supply.
• At 01:16 — Bill describes how traditional success metrics in agriculture hide a deeper story of burnout, consolidation, and loss of diversity.
• At 02:14 —...
