Yellowstone Herbarium

The Yellowstone Herbarium (YELLO) contains mainly plants collected in Yellowstone National Park. Our herbarium specimens document the presence of plants in the park over time, and the history of plant collecting in the park, making it an incredibly valuable resource for staff, visitors, and researchers.

The Yellowstone Herbarium is located in the Heritage and Research Center in Gardiner, Montana. Our collection includes: vascular and non-vascular plants, fungi, and lichens. Our oldest specimens date back to 1899 and traveled to the World Fair in 1903. We have over 12,000 specimens including collections of aquatic plants and non-vascular plants, both of which are some of the best collections in the Rocky Mountains. Yellowstone herbarium may now likely have the most comprehensive scientific collection of native aquatic vascular plant specimens in the western United States. We have multiple scopes and reference material that are available to use during the hours the herbarium is open.
