Obtain historic collection summaries.
All historic accession cards, from Abeliophyllum to Zizyphus, have been reviewed and incorporated into BG-BASE, resulting in almost 70,000 new and over 100,000 edited records. In addition, 1,700 map documents (ca. 1937–1988) representing 1,982 locations have been digitized.
The Horticultural Library is a specialized research collection that supports the curation, documentation, and study of the Arboretum’s plants and serves the Harvard community, Arboretum members, and the public.
Only a minority of the accessions ever attempted to be grown in the collections of the Arnold Arboretum are currently alive—some perished over the past 140 years, while others representing propagules (seeds, cuttings, etc.) may have never grown to maturity. However, the records associated with these legacy collections still hold immense value in documenting the history of plant introduction, since the Arboretum facilitated the initial point of entry in North America for many plant species. Thus, colleague institutions can use these legacy collections records to augment their own plant records.
