Plan Your Holiday Visit

Season's Greenings: National Parks and Historic PlacesImmerse yourself in the sights, smells, and sounds of the season in our annual holiday show Season's Greenings. See thousands of blooms throughout the Conservatory from exotic orchids to a showcase of heirloom and newly developed poinsettia varieties. Throughout the Conservatory, we will celebrate the 100th anniversary of the National Park Service and the 50th anniversary of the National Historic Preservation Act, including displaying one of the largest indoor trees decked out with ornaments from national parks. In this year's model train show, the trains will chug around, below, through, and above plant-based recreations of iconic national parks and historic places. See the Grand Canyon, Old Faithful Inn, the Gateway Arch, Mount Vernon, the Statue of Liberty, and many more. Our collection of D.C. landmarks, all made from natural materials, will return to fill the Garden Court. Join us as we celebrate the holidays and America's natural and cultural treasures.

Season's Greenings: National Parks and Historic Sites runs from Thanksgiving Day, November 24, 2016 to Monday, January 2, 2017. The best times to visit Season's Greenings are weekdays early in December or on select Tuesday and Thursday evenings in December when the Conservatory is open until 8 p.m. with live seasonal music.

Aside from these extended holiday hours, the Conservatory is open every day of the year, from 10 a.m. to 5 p.m., free of charge.

Please travel lightly, as the Conservatory is not equipped to store your personal items. You must keep strollers and all personal items with you at all times.


We welcome - and encourage - personal photography at the U.S. Botanic Garden. Due to the increased number of visitors to the Garden during Season's Greenings, tripods cannot be used on any weekends or on weekdays from the middle of December through the end of the exhibit.

Commercial photography - including wedding, engagement and professional family photography - is not allowed in the Garden at any time of the year.


Group tours are not offered during Season's Greenings, but resume in January each year after the holiday exhibit is over.


During Season's Greenings, there are two entrances to the Conservatory on Maryland Avenue SW.

  • The Model Train Entrance provides entry to the model train exhibit. After you've seen the trains, you can view the rest of the Season's Greenings: Pollination Station exhibit throughout the Conservatory.
  • The Conservatory Entrance bypasses the main train display and provides entry to the rest of the Conservatory. You'll find seasonal plant displays throughout the Conservatory, replicas of the capital's landmark buildings in the Garden Court and one of the largest indoor decorated trees in Washington, D.C., in the West Gallery.

In short, if you want to see the model trains, please use the Model Train Entrance.
