Established in 1892, the University of Idaho Stillinger Herbarium is the largest herbarium in Idaho and functions as the official state repository for more than 200,000 plant and fungal specimens.

The herbarium’s collections contribute to a wide variety of research at the University of Idaho and beyond, supporting research in systematics, ecology, floristics, conservation biology and natural resource management, and the herbarium and its resources are used for both formal and informal teaching and learning at the University of Idaho.

We are located on the Moscow campus in the Mines Building #116 and #117 on the ground floor.

Our current hours are Monday through Friday 9 a.m. to 5 p.m. or by appointment. Please contact Kai Battenberg at herbarium@uidaho.edu for inquiries.
