Poinsettias and holiday decorations at the U.S. Botanic Garden

Season's Greenings: America's Gardens!

November 28, 2019 - January 5, 2020

Join us to explore botanic gardens from Hawaii to Maine in this year’s Season’s Greenings holiday show! Plant based recreations of conservatories, fountains, and sculptures will fill the model train room. These will include iconic gardens scenes like Brooklyn Botanic Garden’s vibrant red Japanese torii gate, Franklin Park Conservatory and Botanical Gardens’ flamingo topiaries, Missouri Botanical Garden’s famous Climatron conservatory, and Huntsville Botanical Garden’s Rocket Gardenfeaturing NASA space nodes and rockets! The Conservatory will be filled with thousands of flowers, 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, and the West Gallery will feature a decorated tree with its own model train. Join us as we celebrate the holidays and America’s beautiful and diverse public gardens.


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.

Holiday Gift Shop and Hot Beverages

Two new elements this year courtesy of the Friends of the U.S. Botanic Garden (Friends) will be a gift shop and coffee, tea, and hot chocolate available for purchase on the front terrace near the wait line for the model train display. The Friends' gift shop will offer items such as ornaments, post cards, chocolates, books, and other educational and botanical gift items, and will be open every day from Dec. 5 through Dec. 23. The Friends' hot beverage stand will be run by local coffee roaster Zeke's Coffee and will be open all weekends throughout the exhibit and daily December 13-January 1. Proceeds from the gift shop and beverage stand will benefit education programs at the USBG.


Accessibility - Access Pass

During Season's Greenings, the annual holiday show, the U.S. Botanic Garden experiences high visitation, especially through the model train display which requires a separate entry point. Individuals that are unable to wait in line due to physical, sensory-processing and/or brain-based disabilities and their companions, may request, in advance, an access pass to advance through the line. As a courtesy, we ask that you limit the party size to six individuals. At this time, all access passes must be requested in-person at the information desk. 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 at the front of the building 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 one of the largest indoor decorated trees in Washington, D.C. 

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.
