Celebrate the seasons and learn about both native and cultivated plants at these public gardens in Pennsylvania.

A public garden is not merely a nice collection of plants—it’s a space where horticulture inspires both learning and fun. In contrast to private or commercial gardens, public gardens grow plants “for the purposes of public education and enjoyment, in addition to research, conservation, and higher learning,” per the American Public Gardens Association. More than two dozen public gardens in Pennsylvania are members of the association and are dedicated to botanical beauty alongside community enrichment. We’ve put together a list of the public gardens in Pa. that you can visit in all their glory this spring.

Public gardens in Western Pennsylvania

Pittsburgh Botanic Garden

Pittsburgh Botanic Garden only opened in 2015, but it’s already captured the hearts of Pittsburghers interested in sustainability: The outdoor garden was built on land previously used for coal mining. The restored land now showcases plants native to the Allegheny Plateau as well as cultivated gardens like the Asian Woodland and its lotus pond and the Garden of the Five Senses. As its name suggests, the Garden of the Five Senses invites visitors—children and adults alike—to use each of their senses to explore the woodlands.
