What is a herbarium?

A herbarium is a systematic arranged collection of dried and pressed plant specimens mounted on a sheet of paper along with associated important field data (place and date of collecting, scientific name, collector’s name etc.). The specimens may be a whole plant or plant parts. The specimens are filed according to families and genera and are available for ready reference.

The herbarium in Johannesburg Botanical Garden (JBG) currently houses more than 6 000 specimens and is used by JCPZ employees and the broader community (i.e. residents; students and researchers) for plant identification, educational and research purposes. About 70% of the specimens in the JBG herbarium represent the vegetation of City of Johannesburg and the oldest specimen was collected in 1901. Collection of specimens is on-going. Next to the herbarium, the seed room houses seed collection used for conservation, educational and research purposes.
