About Us

Volunteers collecting in the Washington Park Arboretum

The Otis Douglas Hyde Herbarium collects and houses pressed plant specimens of accessioned plants in the UW Botanic Gardens, as well as specimens that reflect the research of students, staff and faculty.  The Herbarium also harbors the Washington State Noxious Weed Control Board’s collection.

These collections are vital to science.  Herbarium specimens provide information about plants in our past and present environments.  They offer a view over decades and centuries that allow scientists to study the extinction of plants, track invasive species, and even shed led on climate change through phenology.  The Herbarium is a storehouse of botanical DNA from the Seattle region, the Pacific Northwest and beyond.
