Season's Greenings: All Aboard!

November 22, 2018 - January 1, 2019

This year, take a train ride across America as our annual holiday show Season’s Greenings showcases train stations! Plant-based recreations of iconic train stations from across the United States will be represented in the train room. Explore classic stations like New York City’s Grand Central Terminal, St. Louis’ Union Station, and many more. Thousands of blooms will be on display throughout the Conservatory, including a showcase of heirloom and newly developed poinsettia varieties. Our collection of D.C. landmarks made from plant materials will return to fill the Garden Court, this year including a botanical version of Washington, D.C.’s Union Station. Join us as we celebrate the holidays and America’s railroad history. Please note: Due to the ongoing roof and façade project in the Conservatory, waiting time to enter this year’s holiday show may be longer than usual.


Hours and Holiday Concerts

The Conservatory is open every day of the year, from 10 a.m. to 5 p.m., free of charge. The best times to visit Season’s Greenings are weekdays early in December. On select Tuesday and Thursday evenings in December, the Conservatory is open until 8 p.m. with live seasonal music. Please travel lightly, as the Conservatory is not equipped to store personal items. You must keep strollers and all personal items with you at all times. More information about visiting (directions, etc.) »


Accessibility - Access Pass

The popular model train display requires a separate entry point often resulting in a line. Individuals and caregivers of visitors that are unable to wait in line due to sensory-processing and/or cognitive developmental disabilities may request, in advance, an easy access pass to advance through the line. As a courtesy, we ask that you limit the party size to four individuals. Sensory-friendly programs are scheduled during the holiday show that provide entrance for registered participants, pre-visit materials, and a take-a-break space. Please contact Maura Nelson, or 202-226-1047 for more information on the easy access pass or sensory-friendly programming. For additional information, please visit our Accessibility page.


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 throughout the run of the exhibit.

We do not allow visitors to do photoshoots or videoshoots at the Garden. Please read the full Photography and Art Policy for more details.


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 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 two of the largest indoor decorated trees in Washington, D.C. Due to stone and roof restoration work, the large trees are in the Garden Court and not the West Gallery. As such, there is no train around the tree this year. Find all the trains in the West Gallery using the Model Train Entrance.

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


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