Summer evening hours are well underway, but we’ve already heard how impactful they have been to you and thousands of other visitors to the National Arboretum. If you want to protect and expand access to the Arboretum through programs like this one, please donate to FONA today.

We couldn’t host this program without supporters like you. When you donate today, your gift will support 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.

Go above and beyond by sponsoring a night! Donations 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 beauty and science of the U.S. National Arboretum!

Last week marked the final SPROUT field trip of the spring 2026 season! Science Program Reaching OUT (SPROUT) is FONA’s school year field trip program that invites children to explore the Washington Youth Garden and learn hands-on garden science. So far this year, we’ve hosted 984 students through 27 total field trips. Students ranged from grades Pre-K through 6th, with a majority of the schools coming from D.C. Wards 6, 7, and 8.



On SPROUT trips, children get up close and personal with plants and insects — observing worms busy creating compost, feeling the fuzzy leaves of plants, and tasting strawberries straight from the vine. Program Manager Mariyah Whitley explains that she loves watching kids become more comfortable outside in the garden over the course of just a few hours. “A lot of the kids start out super afraid of bees. But after learning more about bees and tasting some honey, some of them even want to open up the hive to get a closer look!” shares Mariyah.
