History and mission
Established in the early 20th century by an act of Congress, the Arboretum was created to support plant research, conservation and public education. Over decades it has grown into both a cultural landmark and a scientific facility, preserving heritage specimens and developing improved cultivars while documenting plant performance in the mid-Atlantic climate.
Research, education and public use
The Arboretum is operated as a center for horticultural research and offers outreach programs, workshops, tours and seasonal displays. Scientists there work on plant taxonomy, pest management, conservation of rare species and breeding of disease-resistant landscape plants. Visitors can follow trails, join guided walks, and attend family and school programs that promote plant literacy.
Open to the public with no general admission charge, the Arboretum functions as both a living classroom and a recreational green space in the nation's capital. For visitor details, maps and events consult the official visitor information: visit the Arboretum site.
