Kathryn Kalmbach Herbarium of Vascular Plants

The Kathryn Kalmbach Herbarium of Vascular Plants (KHD) documents vascular plants from the Southern Rocky Mountain Region.

Before Denver Botanic Gardens was established, the Kathryn Kalmbach Herbarium of Vascular Plants was founded by local plant enthusiasts working to document the wild and cultivated flora of Colorado through scientific specimens. Now 70 years old, KHD holds nearly 70,000 specimens collected across Colorado and the greater Southern Rocky Mountain Region. KHD also includes a small ethnobotany collection which documents how people use plants for medical and spiritual purposes, among others. 

Kathryn Kalmbach Herbarium of Vascular Plant specimens are discoverable online through SEINet, an external database used by herbaria across North America.

Using specimen locality data, we’ve worked with collaborators to create species checklists for popular natural areas across Colorado.
