The beautiful conservatory at the Biltmore Estate was completed in 1895 and highlights a wide variety of exotic plants. Its tall arched windows look out onto the terraced butterfly garden and the Walled Garden beyond, and the pointed glass roof lets in an abundance of natural light. (From the conservatory website)

We visited the “Season’s Greenings: America’s Gardens!” exhibit at the United States Botanic Garden, featuring plant-based recreations of conservatories, fountains and sculptures from around the country, with model trains running around and above the displays. It's become an annual event for us, and we always enjoy the holiday creations as well as the traditional DC landmarks display (most of which I didn't photograph again this year) as well as the 3,000-plus varieties of pointsettias gracing the various halls.
Best to view in "Original" because other versions resized by Pbase are decidedly unsharp.
