View a short video about this garden.

The Arboretum’s Pollinator and Bird Garden, which opened in July 2021, is unique in its ambitious design and intent: to educate the public about the many insect pollinator species and both resident and migratory birds in our region, and research ways to protect the ecosystems that support these species. The planting design showcases over 390 unique plant species and varieties—most of which are native to Pennsylvania or the greater Appalachian region. Read more about this garden.
