Thursday Night Nature: Collaborating with Nature: A Botanical Art Garden Grows at Herrontown Woods with Steve Hiltner (Apr. 27)

Years of institutional neglect had left the first nature preserve in Princeton, NJ, unusable—its trails overgrown, historic buildings boarded up and the parking lot a staging ground for crime. Ten years ago, three volunteers formed a nonprofit, Friends of Herrontown Woods, and began clearing trails and cutting invasive species. When storms blew down a pine grove next to the parking lot, the Friends saw an opportunity to create something special. Without a budget, invasive growth was quelled, paths grew and a forest opening took shape, now home to 150 native plant species. Artists helped combine nature and culture to create a place of whimsy, beauty and discovery. This is a story of persistence, serendipity, incrementalism, combining physical work and intellect to build a community through stewardship. The Barden has become a place to learn about and collaborate with nature—the most generous and creative force of all.


Steve Hiltner has degrees in botany and water quality and has founded and led two nonprofits: a watershed association in Durham, NC, and the Friends of Herrontown Woods in Princeton, NJ. He has planted and maintained prairies in Michigan and wetland gardens in North Carolina floodplain parks. In Princeton, he has restored habitat, converted detention basins to native wet meadows, performed ecological assessments in preserves and has written over 1500 posts at PrincetonNatureNotes.org. Hiltner is also a professional jazz musician and composer who has written and performed climate change theater.

Living in a Liberated Landscape with Larry Weaner (November 11, 2023)

This program is brought to you, in part, thanks to the generous support of the Bucks County Foundation.

All too often in our gardens and landscapes we think of static compositions of carefully placed and managed plants. But our approach can be more dynamic—and arguably more rewarding—by taking advantage of natural plant abilities to reproduce and proliferate. Learn how designer Larry Weaner, FAPLD, combines design with the reproductive abilities of plants and ecological processes to create compelling, ever-evolving landscapes that bring new meaning to partnering with nature. Using examples from his own property and diverse client projects, Weaner will share how this give-and-take approach can result in compelling, low-maintenance landscapes that free plants to perform according to their natural abilities and liberate people from having to cater to their landscapes’ every need. 

Larry Weaner, FAPLD, founded Larry Weaner Landscape Associates in 1982 and established New Directions in the American Landscape in 1990. He is nationally recognized for combining expertise in horticulture, landscape design and ecological restoration. His design and restoration work spans across the U.S. and in the U.K. and has been profiled in numerous national publications. His book Garden Revolution: How Our Landscapes Can Be a Source of Environmental Change (Timber Press, 2016) received an American Horticultural Society (AHS) Book Award in 2017. In 2021 he received AHS’s Landscape Design Award and the Association of Professional Landscape Designers (APLD) Award of Distinction.
