The Herbarium of Cultivated Plants is a collection within the Herbarium of the Arnold Arboretum (A). Allied with five additional collections, the resources of the Harvard University Herbaria comprise one of the largest comprehensive collections of algae, bryophytes, fungi, and vascular plants in the world.

As of January 2016, the Herbarium of Cultivated Plants contained 129,199 specimens. Of these, 48,204 specimens document extant and historic accessions while 80,995 non-Arnold Arboretum specimens have been amassed from cultivated sources across North America, Asia, and Europe. The Spontaneous Flora Collection, comprised of 2,235 specimens collected from spontaneous vegetation on the Arboretum grounds, is also housed here. Specimens collected from Arboretum accessions are searchable using Plant Search.

Management and development of the collection is guided by the Cultivated Herbarium Collections Policy [pdf].
