News & Events

PHONES & BOTANICAL EXPLORER ISSUES: Our phone system is currently experiencing intermittent issues with both incoming and outgoing calls. Also, all unanswered calls are not going to voice-mail, further exacerbating the issue. Our online Arboreum Botanical Explorer (A.B.E.) is currently back online. Thank you for your patience with both of these current challenges.
Please note our new hours!

The grounds are open to the public Fridays through Mondays from 8:00 am to 5:00 pm; the National Bonsai & Penjing Museum is open from 10:00 am to 4:00 pm. Please see our Hours and Admission page for additional information. We look forward to seeing you at the National Arboretum, where science meets beauty.
