Herbarium of Cultivated Plants Initiatives
Approximately 500 voucher specimens, collected from Arboretum accessions, are added to the herbarium annually. Documenting accessions in flower and fruit, vouchers record the growth, development, and performance of plants in the collection and are essential tools for identity verification. At present, curatorial staff are working to voucher Plant Collections Network holdings. Vouchers are also collected from plants used for scientific study in an ongoing effort to document the research use of the living collections.
