Cultivated Herbarium

Herbarium of Cultivated Plants 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 Plant Collections Network holdings. Voucher specimens are also collected from plants used for scientific study, documenting the research use of the Living Collection.
