Our popular annual holiday display “Season’s Greenings” will feature model trains in the gated outdoor gardens, festive lights throughout the Garden, and the Conservatory will feature poinsettias, holiday decor, and D.C. landmarks made from plants. On the lawn in the gated outdoor gardens, G-gauge model trains will circulate from 10:00-5:00 daily through displays of pollinators made from plant parts. These scenes will range from oversized models of native U.S. flowers, butterflies, bats, and hummingbirds to an orchid bee pollinating a vanilla orchid flower, a chocolate midge pollinating a cacao flower, a lemur pollinating a traveler’s tree flower, and more! The Garden will be closed on December 25.
