The oldest-known extant orangery in American can be seen at the
Wye Plantation, near Tunis Mills (Easton), Maryland. This orangery sits behind the main house and consists of a large open room with two smaller wings added at some point after the initial construction. The south-facing wall consists of large triple-hung windows. A second story was traditionally part of the style of orangeries at the time of its construction in the middle to late 18th century as a way of further insulating the main section where the plants were kept. According to the current resident, Ms. Tilghman (a descendent of the Lloyd family), it served as a billiards room for the family. This plantation is also notable as having been the home of
Frederick Douglass as a young slave boy. The orangery is described in the book
Glass Houses, as is the orangery at Mount Airy.
Ms. Tilghman notes that plants are still stored inside the building in winter, but a frame has been constructed to hold the houseplants, and the whole of the frame is covered with plastic to keep in moisture. In this way, the plants do not have to be watered through the entire winter.
Another orangery stands at
Hampton National Historic Site near
Towson, Maryland. Originally built in 1820, it was part of one of the most extensive collections of citrus trees in the U.S. by the mid-19th century.
[15] The current structure is a reconstruction built in the 1970s to replace the original, which burned in 1926.

The orangery at the Battersea Historic Site in
Petersburg, Virginia is currently under restoration. Originally built between 1823 and 1841, it was converted into a garage in a later period.

An 18th-century style orangery was built in the 1980s at the
Tower Hill Botanic Garden in Boylston, Massachusetts. Another early 19th century example can also be seen at
Dumbarton Oaks in Washington, D.C. It was built in 1810, and is now used to house gardenias, oleander and citrus plants during the winter.
