On a summer Saturday at Bowman's Hill Wildflower Preserve, a small cohort gathers to learn what makes a plant 'invasive,' how these exotics alter local ecosystems, and how to manage them without relying on chemicals. The Knowing Native Plants session pairs field identification with practical control techniques and the larger case for native planting in the Delaware Valley.
