Season's Greenings Holiday Exhibit Opening (U.S. Botanic Garden)

About this adventure

A beloved Thanksgiving Day tradition for generations of Washingtonians, the U.S. Botanic Garden officially debuts its breathtaking annual 'Season's Greenings' holiday showcase on Thanksgiving morning. Nestled at the foot of the U.S. Capitol, the historic Conservatory transforms into a verdant wonderland filled with thousands of vibrant poinsettias, orchids, and evergreen boughs. Kids and train lovers of all ages will be enchanted by the G-gauge model train display winding through whimsical botanical landscapes. Inside the West Gallery, marvel at meticulously detailed miniature replicas of D.C. landmarks—such as the Capitol Building, White House, and Lincoln Memorial—crafted entirely from plant materials like acorns, bark, seed pods, and pine cones. Wide, accessible pathways make it exceptionally stroller-friendly.
