Our popular annual holiday display “Season’s Greenings” features model trains in the gated outdoor gardens, festive lights throughout the Garden, and the poinsettias, holiday decor, and D.C. landmarks made from plants inside the Conservatory. On the lawn in the gated outdoor gardens, G-gauge model trains circulate from 10:00-5:00 daily through displays of pollinators made from plant parts. These scenes range from oversized models of native U.S. flowers like milkweed and bats pollinating a banana 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.
