Father’s Day Forest Bathing

Join us for a calming forest bathing walk at the National Arboretum this Father’s Day (June 21st) from 9 AM to 11 AM. This special session coincides with the summer solstice, a time of growth and energization. During the walk, you’ll practice breathing mindfully amongst the plants as you soak up the powerful, revitalizing energy of the sun. Give the gift of relaxation to the father figure in your life! Registration is required and tickets cost $35.

Support Summer Evening Hours!

Last summer, more than 40,000 visitors took advantage of FONA’s summer evening hours at the National Arboretum. So many people shared how important it is for them to have access to the Arboretum after a long workday. It means more time with friends and family, more time for physical and mental health, and more time outdoors during the hottest part of the year.


This program is only possible because of supporters like you. Donate today to support summer evening hours! Your gift of any size will make a huge impact for things like:

  • Extended Access: Keeping the gates open later for working families and visitors with busy schedules.
  • Vital Operations: Funding the evening staffing, operations, and visitor services required to stay open late.
  • Community Connection: Creating more opportunities for people to experience nature in the heart of D.C.


Want to sponsor a night? Gifts of $1,000 or more will sponsor an entire evening of extended hours. You'll receive special name recognition on our website through August 2026.


Thank you for helping more people experience the U.S. National Arboretum. Let’s make this summer unforgettable, one sunset at a time.

Capitol Columns History

Sitting on a grassy knoll and pointing straight up into the sky, the National Capital Columns are an unusual but stunning sight at the National Arboretum. This set of twenty-two Corinthian columns is arguably the most iconic landmark at the Arboretum, but have you ever wondered how they got there? In anticipation of America’s 250th anniversary, news outlets have shone a spotlight on the history behind these columns. Hear from Dr. Richard Olsen, Director of the U.S. National Arboretum, in this video produced by NBC4 Washington

Plant Spotlight

Hydrangeas are essential shrubs for any garden, with lovely, long-lasting bracts and handsome foliage. While mophead hydrangeas are popular for their colorful mounds of flowers and small stature, they are mostly sterile and therefore unpopular with pollinators. Lacecap and panicle hydrangeas are much more inviting, with clumps of fertile, nectar-filled flowers surrounded by attractive bracts. The native oakleaf hydrangea, Hydrangea quercifolia, is a panicled hydrangea that does well in many gardens. However, the Asian Hydrangea paniculata is more tolerant of sun, salt and pollution. It is a better choice in colder climates, clay soils, or soils that periodically get very wet.

It grows up to 25 feet tall, covered in large flower panicles with bracts that open white and turn rosy-pink over the course of the summer. The dried flowers and bracts remain intact and can be kept over winter to extend ornamental value until the following spring. Panicled hydrangeas bloom on new growth and handle pruning quite well, so they can be maintained at smaller sizes. Visit a well-pruned Hydrangea paniculata in the Asian Collections or full-sized specimens in the Dogwood and Azalea Collections at the U.S. National Arboretum.

New Slovenian Beehive at the Washington Youth Garden

In honor of World Bee Day last month, His Excellency Iztok Mirošič, Ambassador of the Republic of Slovenia to the United States, presented a Slovenian beehive to be added to the Washington Youth Garden. Slovenia is known worldwide as an epicenter of beekeeping innovation. Slovenian hives are uniquely structured, using cabinets that are accessible from behind to minimize heavy lifting and improve accessibility. They also feature colorful painted panels that are an expression of Slovenian folk art and often tell stories of beekeepers’ daily lives. 


Thank you to DC Beekeeper’s Alliance for painting the front panels of this new hive and helping to move in a new bee colony. We are so excited for our apiary to grow! FONA’s team will use the new hive to teach visitors about the important role pollinators play in agriculture and ecosystem health around the world. We are grateful for this opportunity to expand our work connecting people with nature across cultures — through the uniting power of food.
