GARLIC PLANTING PARTY & BULB SALE

Our annual Garlic Planting Party & Bulb Sale is a great way to celebrate fall and FONA’s community at the National Arboretum! This event takes place each year in the Washington Youth Garden on the last Saturday in October. Attendees can plant garlic, harvest sweet potatoes, try fresh sugar cane juice, and enjoy free nature-based family activities. They can also buy edible and ornamental bulbs to plant in their own gardens. We will share information about the 2026 event in the late summer or early fall of 2026.

WINTER FESTIVAL & CHRISTMAS TREE SALE

Get in the holiday spirit with FONA’s Winter Festival & Christmas Tree Sale! This important annual fundraiser supports our work at the National Arboretum. We hold this event each year in early December. We will share more information about the 2026 Winter Festival & Christmas Tree Sale in the late summer or early fall of 2026.

LAHR NATIVE PLANT SYMPOSIUM & NATIVE PLANT SALE

The National Arboretum’s Lahr Native Plant Symposium brings together expert speakers for an engaging day of presentations about native plants, wildlife, and ecosystems. FONA’s Native Plant Sale hosts a small number of native plant vendors from across the mid-Atlantic region to sell spring ephemerals and other choice perennials and woody plants. These events are held in conjunction with each other in late March. Information for the 2027 events will be announced in early 2027.

BECOME A VENDOR

Apply today to be a vendor at one of FONA’s 2026 seasonal festivals! Our seasonal festivals draw thousands of visitors to the National Arboretum throughout the year. Each event is unique: the Native Plant Sale connects with native plant enthusiasts; the Garden Fair & Plant Sale provides everything a gardener needs to get growing in the spring; and the Winter Festival offers holiday cheer and a gift market. Apply today if you are a local business, nursery, or food truck interested in vending at one or multiple 2026 seasonal festivals. A limited number of booths are available at each event and space fills quickly.
