Background

The Arnold Arboretum’s living collections are celebrated as some of the most comprehensive and best documented of their kind. Its rich holdings include temperate ligneous plants from around the world. Many of the plants originate from collecting expeditions, others derive from horticultural experimentation, and some were existing vegetation when the Arboretum was founded in 1872. Each of these plants—some 16,000 in all—has a story to tell, and they are preserved as both scientific and horticultural specimens to enrich our understanding of biodiversity through the institution’s research, education, and outreach efforts.
