Phipps Conservatory and Botanical Gardens

Paper cranes on display in the Palm Court

The Palm Court is the first room visitors see after entering the Conservatory through the main entrance. The Victorian-inspired room contains many species of palm trees.[12] The room contains the original dated plaque from the Conservatory's opening as well as numerous glass installations by Dale Chihuly. To accommodate the palm trees, the Palm Court has a high glass peak.

The original wood and annealed glass in the Palm Court had deteriorated to a point for the need of emergency stabilization in 2008.[13] Renovations began in 1992 and included replacing the upper wood and glass vent sash with aluminum and safety glass, and replacing the vertical wood and glass components with new replicated aluminum extrusions and safety glass glazing to match the original specifications exactly.

The Serpentine Room during the winter flower show

The Serpentine Room is located west of the Palm Court, connecting it to the Fern Room.[14] The exhibits in the room change with the season for different shows and special exhibits. The room is named for its curved brick-walled pathway. Plants are lined along either side of the pathway, as well as suspended from the peaked ceiling.

The room was originally known as the Border Garden, which was redesigned as the present-day Serpentine Room during an 18-month period of extensive renovations starting in 1978.[15]

The Fern Room is located in the west wing at the intersection of the Serpentine Room, the Orchid Room, and the Stove Room.[16] The room contains many ferns, as well as cycads and other ground plants on which ferns commonly grow. The dominant species in the room are representative of the Triassic, during which ferns and cycads were common as flowering plants would not evolve until millennia later. Some species include Munch's cycad, Eastern Cape cycad, Zululand cycad, Queen sago, Staghorn fern, Australian tree fern, Tasmanian tree fern, tongue fern, bear's paw fern, and rabbit foot's fern.[17]

The Orchid Room

The Orchid Room is located in the north part of the west wing.[18] The room contains many orchids. This includes the miniature orchids and the Barbara Tisherman Slipper Orchid Collection, curated in collaboration with the Orchid Society of Western Pennsylvania. Also on display is the unique Phalaenopsis Frank Sarris orchid, named for the founder of Sarris Candies, a trustee and benefactor of the Conservatory.

The room originated with a donation of 800 rare orchids in 1931 from Charles D. Armstrong, owner of the Armstrong Cork Company.[19] The orchids were then valued at $50,000.

The Stove Room is located in the south part of the west wing.[20] The plants in the room are representative of the deep tropics, and the room is maintained at a temperature of 80 °F (27 °C) during the day and 70 °F (21 °C) during the night.

The fall Garden Railroad exhibit in the South Conservatory

The South Conservatory is located south of the Palm Court.[21] The room houses seasonal flower shows. Since 1999, during fall and winter months, the room transforms into the Garden Railroad exhibit, in which miniature trains wind among a variety of small plants.[22]

Originally called the Economic Room, the South Conservatory was built between 1896 and 1897 as a gift from Henry Phipps.[23] It was then remodelled in the 1930s, during which time the room was partitioned to separate the Gallery and Tropical Fruit and Spice rooms.

The tropical fruit and spice room

The Tropical Fruit and Spice Room is located west of the South Conservatory.[24] The room contains tropical and sub-tropical fruits, nuts, and spices such as citrus fruits, bananas, allspice, papayas, cinnamon and coffee. The marble basin in the center of the room features a Dale Chihuly glass sculpture in purple and celadon.

The Tropical Forest Conservatory, located south of the South Conservatory, is the largest indoor display area of the conservatory. [25] The room features a different region every three years, and contains man-made waterfalls, winding pathways, a fish pond, and interactive learning stations. It is also the site of many of the public programs and special events at the Conservatory. As of 2015, the region features the Tropical Forest Congo exhibit.[26]

The Tropical Forest Conservatory opened on December 6, 2006.[27] The Tropical Forest Conservatory has several interesting features, which make it extremely energy-efficient. It has "earth tubes" running underground to help cool the tropical forest and a solid oxide fuel cell, which efficiently produces 5 kW of electricity from natural gas. In addition, there are computer-controlled shades that block excess sunlight from entering the structure and also help to insulate it at night. The roof is also computer-controlled and many of the glass panes can be opened.

The farmer's market at the Gallery Room

The Gallery Room is located east of the South Conservatory.[28] The room contains didactic displays for children, such as the imaginary farmer's market, where children can play and learn about healthy food.

In the 1950s and 1960s, the room was known as the Modern Room, and featured contemporary room and garden scenes.[29]

The Sunken Garden during the winter flower show

The Sunken Garden is located east of the Palm Court, connecting it to the Victoria Room.[30] The room is furnished with fountains, hanging baskets, and sunken beds. The plants in the room vary with season. The room has changed several times over the decades. It has been known, at different times, as the Cascade Garden featuring a modern cascading waterfall; the Charleston Garden featuring an antebellum-themed display with a Southern mansion façade; and, more recently, a Japanese-style garden.[31]

The Desert Room

The Desert Room is located south of the Sunken Garden.[32] The room contains plant life that thrive in a desert climate, such as cacti and other succulent plants. A glass chandelier named Desert Gold Star by Dale Chihuly can also be found in the room. Some species include the Joshua tree, saguaro, palo verde, fire barrels, cape aloe, tortoise shell plant, bushman poison bulb, African tree grape, sunrise tequila agave, and shaving brush tree.[17]

The Desert Room opened in 1902 as the Cacti House.[33] When it first opened, guests could only look at the display garden over a terrace. In the late 1930s, the room was redesigned so that visitors could walk through it.

The Victoria Room is located in the east wing, connecting the Broderie Room, the East Room, and the Sunken Garden.[34] The room features a large central pond containing an interactive fountain.

The Broderie Room, also known as the Parterre de Broderie which translates to "flowerbed of embroidery", is located in the south part of the east wing.[35] The garden is modelled after the formal gardens of French chateaux during the reign of Louis XIV, and is a popular setting for wedding ceremonies and photo shoots. The room opened in 1939 and was originally called the Cloister Garden.[36] In 1966, the room was redesigned as the present-day Broderie Room.

The East Room is located in the north part of the east wing.[37] The room contains streams and waterfalls. The displays change with season.

The Rooftop Edible Garden

The Rooftop Edible Garden is located between the Desert Room and the Tropical Forest Conservatory.[38] It contains several edible vegetables and fruits. The outdoor demonstration space produces fresh produce for the cafeteria in the Welcome Center and serves as a site of hands-on learning for children's camps and youth programs.

The Japanese Courtyard Garden is located between the Desert Room and the Gallery Room.[39] It contains a Japanese garden and several bonsai. The Garden was installed in 1991 and was designed by Hoichi Kurisu.[40]

Discovery Garden during the winter 2015 light show

The Children's Discovery Garden is located between the Stove Room and the Tropical Spices room.[41] The Garden contains areas designed to attract birds, butterflies, and bees. It also includes a bog garden, a sensory garden, and various outdoor spaces to entertain and educate children.

The Outdoor Garden is located to the northwest of the main building complex.[42] The garden contains many smaller gardens and plant collections, including an herb garden, a medicinal garden, perennials, ferns and dwarf conifers.

The original hardscape was constructed by Works Progress Administration in 1935 and persists to this day.[43] The garden was originally known as the Perennial Garden, which was transformed into the Outdoor Garden in 1986.

The Phipps Hall of Botany

The Botany Hall, across from Panther Hollow Bridge, features a small garden containing walkways, curved benches, and a fountain.[44] The Botany Hall was funded, in 1901, by Henry Phipps to be used by local teachers looking to enhance class trips to the glasshouse.[45] It was renovated in the late 1990s and continues to serve as a site for many educational programs and events.

The Aquatic garden is located on the east side of the Conservatory outside of the Victoria Room.[46] During the summer, the two pools are filled with tropical water plants and floating flora. One of the pools features a statue of Neptune, the Roman god of the sea, which was presented to Phipps shortly after the conservatory opened in 1893. The northern pool was constructed sometime between 1910 and 1915, and the southern one was added in 1939.[9]
