Explore the plants of the holidays with us! This year’s “Season’s Greenings” features thousands of poinsettias, D.C. landmarks made from plants inside the Conservatory, model trains in the outdoor gardens, and festive lights and decor throughout the Garden. In the gated outdoor gardens, G-gauge model trains chug from 10 a.m. to 5 p.m. daily through pollinator sculptures made from plants, showcasing an orchid bee pollinating a vanilla orchid flower, a lemur pollinating a traveler’s tree flower, a bat pollinating a banana flower, pollinators of native U.S. flowers like milkweed and lobelia, and more!
