November 28, 2013 through January 5, 2014 — The U.S. Botanic Garden’s annual holiday exhibit, Season's Greenings, is on display November 28 through January 5. On display at the Conservatory are models of D.C. landmarks made from plant materials, a showcase of poinsettias and a grove of conifer trees, and one of the largest indoor, decorated trees in Washington.
Also not to be missed is the fantasy train display in the East Gallery, which chugs along more than 800 feet of track through imaginative structures created with plant materials. Explore this year's theme, the "World's Fair" and see many familiar creations that resulted from a long history of public exhibitions.
The U.S. Botanic Garden Conservatory is open every day, free of charge. The best times to visit Season's Greenings to avoid holiday crowds are weekdays early in December or on the Tuesday and Thursday evenings in December when the Conservatory is open until 8 p.m. for extended evening hours and live seasonal holiday music. On all other days the Conservatory is open from 10 a.m. to 5 p.m. Get more information about planning your holiday exhibit to the U.S. Botanic Garden.
