Arnold Arboretum
Cultivated Herbarium

Cultivated Herbarium Initiatives

Approximately 500 voucher specimens, collected from Arboretum accessions, are added to the herbarium collections annually. Documenting accessions in flower, fruit, and vegetative states, vouchers record the growth, development, and performance of plants in the collection and are essential tools for identity verification. The Arboretum strives to represent every accessioned plant in the cultivated herbarium. At present the Arboretum’s curatorial staff is working to completely voucher each one our NAPCC holdings by 2017. Voucher specimens are also collected from plants used for scientific study, documenting the research use of the Living Collection.
