Philadelphia, PA 19103
Included with general admission
Experience Botany of Nations, a groundbreaking exhibition that provides a new perspective on the legendary Lewis and Clark Corps of Discovery.
Co-curated with Enrique Salmón, PhD, an ethnobotanist and author of IWÍGARA: The Kinship of Plants and People, and developed with contributions from Indigenous cultural historians, Botany of Nations offers a culturally layered view of the plants of North America.
Collected on the famous expedition, some of the oldest plant specimens in the country today are housed in the Academy’s own Lewis and Clark Herbarium. Learn how the Native Nations Meriwether Lewis met on the trail shaped America’s plant knowledge long before Western scientists claimed these “discoveries.” Centering the voices of Native Nations who have protected and cared for the lands for thousands of years, Botany of Nations presents plants as portals to Indigenous storytelling and knowledge.

Second Saturday of each month
Join Academy educators in discovering how the scientists who contributed to the Academy collections prepared Meriwether Lewis for his journey west and how the specimens collected came home to the Academy.
The Lewis and Clark Trail Junior Ranger program is available at more than 30 locations along the 4,900 mile Lewis and Clark National Historic Trail. To earn a Junior Ranger badge, you'll work on an activity booklet. Activities will guide you to check out the place you're visiting and to find out why that place is important to the Lewis and Clark Expedition story. As you fill in the blanks, you'll learn about Native lands. As you decode messages, you'll get to know expedition members’ diverse backgrounds and skills. Join Academy educators in discovering how the scientists who contributed to the Academy collections prepared Meriwether Lewis for his journey west and how the specimens collected came home to the academy.
Junior Ranger programs connect kids and their families to the people, places, and stories of the National Park Service.

As the oldest herbarium in the Americas, the Philadelphia Herbarium (PH) at the Academy of Natural Sciences of Drexel University holds 1.4 million dried plant and fungal specimens dating from the 18th century to the present day. Come learn about the old school and modern ways in which we preserve these incredible plants, from the crafting of a specimen to databasing and even DNA sequencing and see an interesting array of specimens from across the tree of life and through time—including a peek at the Lewis and Clark Herbarium to see plants not featured in the exhibition.
Explore climate justice and sustainability through films, talks and community events.
