About Us
The U.S. National Arboretum’s mission is to enhance the economic, environmental, and aesthetic value of ornamental plants through research, conservation, and display. The U.S. National Arboretum is a collections-based research facility and public garden of the U.S. Department of Agriculture (USDA). 451 acres of rolling forested terrain, and expansive meadows. Nine miles of winding roadways and many more paths connect the gardens and natural areas across the grounds. The display gardens at the National Arboretum grew organically from our early research interests into specific plant groups and collaborations with garden clubs and plant societies into comprehensive collections focused on plant groups important to American landscapes and on important, botanically rich temperate flora. Examples of the latter include the Asian Collections, highlighting plants from China, Korea, and Japan, and Fern Valley, our collection of eastern North American native plants in a scenic woodland settling. Visitation is approximately 710,000 per year.
Duties & Responsibilities
The National Arboretum is a public garden facility. Interns will assist staff in the development and maintenance of the plant germplasm collections. Duties include general gardening tasks–including but not limited to weeding, planting, watering, mowing, mulching–and assisting staff with updating plant records and labels in collections. Internships will involve heavy lifting, repetitive tasks, and exposure to extreme heat, humidity, and/or cold.
