The York Street gardens will close at 3 p.m. on Aug. 18 and 19 for concerts, and close at 3 p.m. on Aug. 23 for a private event.
These collections document vascular plants and fungi from the Southern Rocky Mountain Region. The herbaria hold historic collections, uncommon species, and recent collections. Sam Mitchel Herbarium of Fungi is one of the most diverse, well-collected and actively curated fungal collection in the region. The Gardens natural history collections also include a small ethnobotany collection and an insect collection. Within two years, these collections will move to the Freyer - Newman Center, which will allow the collections to continue to grow and be accessible to researchers and the public.
Free docent-led tours of the natural history collections are usually offered twice a month on Fridays at 1 p.m.
Herbaria are open to the public Monday-Thursday, 9 a.m. - 2 p.m. Herbaria are located in the basement of the Boettcher Memorial Center. If you would like to use the collection, please contact firstname.lastname@example.org to make an appointment.
Please see our fees for identification services. We do not consult on edibility or identify species for consumption.
Due to the sensitive nature of our specimens, service animals are not permitted in our herbaria. If you have a service animal and would like to visit the herbaria, call 720-865-3593 to make an appointment. We recommend you bring someone with you who can stay with your service animal while you visit the herbaria.
