The term orangery described both a grove of orange trees and a structure in which citrus trees were cultivated. William Bartram used the term in 1791 to describe a grove of native trees left standing within a cleared ground and incorporated into a designed plantation, and, therefore, a natural feature in the landscape. Samuel Johnson (1755) and Noah Webster (1848) defined an orangery as an area where orange trees were planted, or as Ephraim Chambers (1741–43) wrote, “used for the parterre.” John Evelyn, in his 1693 translation of Jean de La Quintinie, used the term to refer to any place stocked with orange trees, whether indoors or out. The most common usage, however, refers to the architecture of plant-keeping houses, often synonymous with greenhouse, hothouse, or conservatory. In this sense, the orangery could be a separate building, or a structure that was either part of or attached to a greenhouse in which citrus and other exotic fruits and flowers were kept [Fig. 1].
The term “orangery” originated in Europe during the sixteenth and seventeenth centuries when citrus fruit was highly valued. The orangery was a showcase for the nobility with the best-known examples found at Versailles, St. Petersburg, and Vienna. In eighteenth-century America, however, the term seems to have been used rarely outside garden treatises. Perhaps its aristocratic associations made Americans reluctant to use it. The more generic terms “greenhouse” and “conservatory” replaced it, as did specific names used to describe its precise contents, such as “pinery” (for pineapples), “peachery,” and “grapery” or “vinery.”
Although several imported treatises contain the term “orangery,” it is conspicuously absent in major American publications by Bernard M’Mahon, C. M. Hovey, and A. J. Downing—except when describing eighteenth-century greenhouses. For example, in 1837 Hovey used orangery to describe Bartram’s by-then venerable century-old greenhouse in Philadelphia. In his “Historical Sketches,” Downing described the eighteenth-century greenhouses at William Hamilton’s seat, the Woodlands, as orangeries. These colonial greenhouses were called orangeries in the nineteenth century because they represented an older building type that was characterized by unglazed roofs. This earlier type of plant-keeping structure, built of stone or brick with large windows and a solid, unglazed roof was found at Wye House [Fig. 2]; Fairhill [Fig. 3]; and Lt. Gov. James Hamilton’s estate, Bush Hill, near Philadelphia. This type had an architectural style consistent with the main house, with a regular entablature and cornice and large windows that were often roundheaded, separated by columns or piers. At the time they were built, they were most probably greenhouses, hothouses, or conservatories, although it is clear that they were used for keeping citrus trees (see Greenhouse and Hothouse for a discussion of heating systems).
This type of greenhouse construction fell out of fashion once gardeners began to realize the benefits of increased light and perpendicular light for growing plants. As a greater proportion of glazing became technically possible with cast-iron construction, the design of plant houses shifted from the shingle-roofed brick or stone orangery to the glasshouse [Fig. 4]. With these changes in structure and material, J. C. Loudon, writing in the early nineteenth century, concluded that the orangery was the greenhouse of the previous century [Fig. 5]. Thus, nineteenth-century authors writing about historical greenhouses distinguished them from the cast-iron and glass structures by calling them orangeries. Twentieth-century garden historians and archaeologists have continued this practice. The orangery, however, did not completely disappear as an option in new construction. Jane Loudon provided a late reference in 1845 when she wrote that the orangery was a house with an opaque roof intended only for orange trees. She asserted the suitability of non-greenhouse construction to that use. Further evidence of the orangery’s continued use is in Robert B. Leuchars’s 1850 Practical Treatise on the Construction, Heating, and Ventilation of Hothouses, in which he described John Hopkins’s very large structure at Clifton Mansion [Fig. 6].
Scholars have pointed out that in the early colonial period, several greenhouses for citrus cultivation were built by wealthy families who had access to international trade networks. It took skill and money to build a good greenhouse for citrus because glass was expensive, servants were required to maintain it, and skilled gardeners needed to cultivate the fruit.  Therefore, they were associated with the privileged and cultured elite [Fig. 7]. Archaeologist Carmen Weber has argued that this association was so well established in the colonial period that in a portrait of Margaret Tilghman Carroll by Charles Willson Peale the simple inclusion of orange leaves was sufficient to symbolize and convey her control of property and considerable wealth.

- “In the afternoon, the most sultry time of the day, we retired to the fragrant shades of an orange grove. The house was situated on an eminence, about one hundred and fifty yards from the river. On the right hand was the orangery, consisting of many hundred trees, natives of the place, and left standing, when the ground about it was cleared. These trees were large, flourishing, and in perfect bloom, and loaded with their ripe golden fruit. On the other side was a spacious garden, occupying a regular slope of ground down to the water; and a pleasant lawn lay between.”

In the construction of all of these the great object is, or ought to be, the admission of light and the power of applying artificial heat with the least labor and expense. ...
- “6171. The orangery is the green-house of the last century, the object of which was to preserve large plants of exotic evergreens during winter, such as the orange tribe, myrtles, sweet bays, pomegranates, and a few others. . . . The orangery was generally placed near to or adjoining the house, and its elevation corresponded in architectural design with that of the mansion. From this last circumstance has arisen a prejudice highly unfavorable to the culture of ornamental exotics, namely, that every plant-habitation attached to a mansion should be an architectural object, and consist of windows between stone piers or columns, with a regular cornice and entablature. By this mode of design, these buildings are rendered so gloomy as never to present a vigorous vegetation, and vivid glowing colors within; and as they are thus unfit for the purpose for which they are intended, it does not appear to us, as we have already observed at length (1590.), that they can possibly be in good taste. Perhaps the only way of reconciling the adoption of such apartments with good sense, is to consider them as lounges or promenade scenes for recreation in unfavorable weather, or for use during fêtes, in either of which cases they may be decorated with a few scattered tubs of orange-trees, camellias, or other evergreen coriaceous-leaved plants from a proper greenhouse, and which will not be much injured by a temporary residence in such places, which, as Nicol has observed, ‘often look more like tombs or places of worship, than compartments for the reception of plants; and, we may add that the more modern sort look like a combination of shop-fronts, of which that at Claremont is a notable example.’ Sometimes structures of this sort are erected to conceal some local deformity, of which, as an instance, we may refer to that . . . erected by Todd, for J. Elliot, Esq., at Pimlico. ‘This building was constructed for the purpose of preventing the prospect of some offices from the dwelling-house. The architectural ornaments, and the roof, not being of glass, are points in the construction not generally to be recommended; but, as it was built for the purpose above mentioned, the objections were overruled. There are three circular stages to this house, which are made to take out at pleasure. The ceiling forms part of a circle, and the floor is paved with Yorkshire stone. It is fifty feet long, and thirteen feet six inches wide, and heated by one fire, the flue from which makes the circuit of the house under the floor.’ (Plans of Green-Houses, &c. p. 10)” [Fig. 9]
- “ORANGERY.—A house intended only for Orange trees may be opaque at the back, and even the roof, with lights only in front, provided the plants be set out during summer. In fact, so that the plants are preserved from the frost, they will do with scarcely any light during winter; and in many parts of the Continent, they are kept in a cellar.”
- “ORANGERY is a green-house or conservatory devoted to the cultivation of the genus Citrus. The best plan for the construction of such a building is that erected at Knowsley Park, and thus described by the gardener, Mr. J. W. Jones. . . . [Fig. 10]
- “‘Measured inside, this house is fourteen and a half yards long, eight broad, and six high. In the centre of the house are eight borders, in which the oranges, &c., are planted; these borders are all marked a. The two borders against the back wall are sixteen inches broad, and three feet deep. The six borders immediately in the centre of the house are fourteen inches broad, and three feet deep; the paths are marked c, the front wall d, and the back one e; p, p, p, represent ornamental cast iron pillars, which, besides supporting the roof, serve also to support light wire trellises; there is one of these pillars in each row for each rafter. The house is entirely heated by smoke flues, two furnaces being placed at f. The dotted lines along the central path show the direction of the flues beneath, from the back to the front entrance, when they diverge, the one entering a raised flue, g, on the right, the other also entering a raised flue on the left. These flues again cross the house at each end, and the smoke escapes by the back wall; it being found inconvenient to place the furnaces in any other situation.
- “‘Two stoves immediately connected with each end of the orangery contain the collection of tropical plants bearing fruit. The communication between these stoves and the orangery is uninterrupted by any glass or other division, so that the orange tribe are subjected to nearly as high a temperature as the tropical plants. The central borders of the orangery, as may be seen in the section, are raised a little above each other, as they recede from the front of the house. The oranges, citrons, &c., are all trained as espaliers; a light wire trellis being stretched from pillar to pillar parallel with the borders, and about eight feet high. The spaces, b, between the borders being about three feet wide, permit a person to walk along between the plants, for the purpose of pruning, watering, &c. These spaces are of the same depth as the borders, and were originally filled with tan; but part of this is now removed, and its place is filled with good soil. In this some fine climbing plants have been turned out, amongst which are several plants of Passiflora quadrangularis, which bear an abundant crop of fine fruit. Besides these, there are also two fine plants of the beautiful new Gardenia Sherbourniae. These, are other climbers, are trained up the rafters, &c., in such a manner as not to materially intercept the light from the orange. The great advantage of having the trees trained on the trellis system is, that every part of the tree is fully exposed to the light, and by planting them in rows one behind the other, a larger surface is obtained for the trees to cover than could be got by adopting any other plan; and consequently, for the space, a larger quantity of fruit is procured. The trees being hung loosely and irregularly to the wires, assume as natural an appearance as circumstances will permit, and the introduction here and there of large plants in pots has a tendency to prevent formality. Two plants are placed in each border.’—Gard. Chron.”
