Plant & Garden Highlights

Plant & Garden Highlights

Since its founding in 1872, the Arnold Arboretum has endeavored to acquire woody plants (trees, shrubs, and vines) from around the world that are potentially hardy out-of-doors in the Boston region. Today the Arnold Arboretum cultivates around 15,000 living plants which represent some 4,000 kinds of trees, shrubs, and vines. Plants are labeled for identification and are largely grouped by family for easy comparison, arranged to follow the botanical sequence proposed by English botanists George Bentham and Joseph Hooker in Genera Plantarum (1862-1883). The diversity of plants and the naturalistic design of the landscape offer exceptional beauty and horticultural interest at all times of the year. In addition to exploring plants by family, visitors are invited to enjoy a number of featured destinations, special horticultural displays, and areas of natural woods within the Arboretum’s 281-acre landscape.
