The Arnold Arboretum is dominated by trees and other woody plants that by and large originated elsewhere— primarily from wild, temperate habitats around the globe. But staff have historically preserved areas of the Arboretum landscape where native understory plants are encouraged to grow spontaneously and by design, and in recent years we have begun collecting and reintroducing herbaceous species that were once common on our grounds. Like our accessioned trees, these plants may be immediately familiar and plentiful in the wild, or threatened and quite rare. One example of a species poised for a comeback in our landscape is New England blazing star, a plant reintroduced through a collaboration with Zoo New England. For the Arboretum, this species is significant to both history and conservation—the last confirmed wild population in all of Suffolk County was documented in our landscape almost 90 years ago.
