Stefan van Norden

Noorden Productions

Stefan Van Norden is a long-time gardener, producer of two films, and podcaster, from Hanover, New Hampshire. His two films, Hand of Brick (2013) and Negotiating with Nature (2017), are both inspired by the realization that nature is not a place one goes to, but rather a place one is already a part of- that we are nature.

Stefan’s interest in further engaging a wider audience with that same message led him to create the podcast Nature Revisited. A podcast which recently celebrated its eighth season, with the publication of its 164th episode.

Nature Revisited has featured conversations with an impressive list of individuals, including Doug Tallamy, Richard Louv, Amy Tan and Bill McKibben from the horticultural world and beyond, discussing their unique connections with nature.

Agenda & Sessions

  • Stefan van Norden - Norden Productions


    Stefan’s journey from a gardener to filmmaker to producing a podcast has brought him closer to a deeper understanding of our relationship with nature. It is more than simply being connected or disconnected with the natural world, rather that, We Are Nature, and need to have a healthier and more responsible relationship with nature and our planet. Stefan will tell about his journey, and how we all must accept this more personal connection with the natural world.
  • Adam Banks

    Pine Barrens, while historically shunned for their low conventional agricultural value, are hotspots of biodiversity which boast incredible beauty and ecosystem services. Located in select spots on the Atlantic coastline, one can observe incredibly unique and resilient plant systems that invite us to both marvel and look more closely. This talk will touch on the history of the ecosystem and examine exceptional plant populations of Pine Barrens, particularly those of New Jersey.

  • Roanne Robbins - Van Berkum Nursery

    Roanne shares lessons learned through years of close observation and time spent in relationship with plants and place. Drawing from experience in gardens, nurseries, and the natural world, Roanne reflects on how sustained attention deepens understanding and reveals the resilience, adaptability, and quiet complexity of New England gardens. Rather than offering fixed answers, the presentation highlights the full breadth of what New England gardens can hold and extends an open invitation to explore. Through lessons learned, stories, and examples, the talk encourages curiosity, inclusivity, and respect for place—suggesting that resilient, expressive gardens emerge when we remain attentive, generous, and open to what plants and landscapes have to teach over time.
  • Marissa Angell - Angell Landscape Architecture


    Marissa will offer a window into ALA's body of work, centering on responsive, energetic landscapes that prioritize quality of life, horticultural sensitivity, and ecological stewardship. This presentation will foreground ALA’s landscape design ethos as a process without a decidedly fixed outcome, exploring the opportunities made explicit by the necessity to convey an ever-evolving medium to a diverse audience.  Using both built work and process as case studies, this talk will challenge the notion of planting as an isolated and static actor in garden-making, and seeks to clarify how ALA views design as a dialogue with natural materials through the construction and stewardship of the landscapes we set in motion.
