mobile appHave you tried our mobile app?


The U.S. National Arboretum mobile app will help guests navigate the vast grounds of the Arboretum via a digital map. A search feature will allow visitors to explore the collections and other features, learn about available visitor services, and locate a memorial bench or tree with greater ease. Tours, exhibits, events and gardens are programmed into the app to let visitors know in “real time” what they can see during their visit. 


Supported by both the iOS and Android platforms, the app will complement the existing signage and other ways of navigating the Arboretum’s many gardens and other features.




eagleAnd then there were two!


On Wednesday March 29th Mr. President and The First Lady welcomed DC4 at 7:21am, with DC 5 hatching the next day, March 30th, at 1:54pm. The eaglets will grow quickly over the coming weeks until they are adult sized and ready to fledge between 10 – 14 weeks of age. We are proud to continue our collaboration with the American Eagle Foundation (AEF), the U.S. Fish & Wildlife Service, DC Department of Energy and Environment, and Alfred State, SUNY College of Technology, on bringing to DC, the Nation, and the world, high-definition eagle nest cameras. Live sound is also captured this year and streamed through several new nest microphones! Check out the live-streaming video and audio at the AEF website. Locally, at the Arboretum, we have added a strategically positioned viewing scope to provide unobstructed views to the eagle nest from below our Azalea collection. So visit in person or via the web as the National Arboretum hosts these majestic animals and their growing family once more.


Azalea Blossom Watch Glenn Dale ‘Zephyr’


Experience the explosion of color when thousands of azaleas at the National Arboretum light up the forest with their subtle shades and colors. The first azaleas begin to bloom in early April with the daffodils and the forsythia, while others are blooming as late as July with the daylilies. We hope that this Azalea Blossom Watch will give you insight into the range and diversity of the Rhododendron species and cultivars growing at the National Arboretum, as well as help you with planning your visit.


The best time to schedule your visit is on a weekday, but if weekends are your only option, a stroll through the garden before noon or during a light rain offers an enviable second choice. Pick up a brochure at one of the three major entrances to the collections or at the Visitor Center and begin your journey into the world of azaleas. Click here for the current status.
