Smithsonian Gardens Orchid Collection
The Smithsonian Gardens Orchid Collection (SGOC) has grown from five plants to over 8,000 specimens since 1974. It is an invaluable resource for educational programs, exhibitions, and scientific research. It is maintained in the Smithsonian Gardens Greenhouse Facility in Suitland, Maryland by staff, interns, and volunteers.
The SGOC received accreditation from the North American Plant Collections Consortium (NAPCC) in January 2014, making it the first member of the Orchidaceae tropical species curatorial group. The conferral of this award indicates Smithsonian Gardens’ dedication to orchid conservation and high collections management standards. Smithsonian Gardens strives to cultivate an extremely diverse array of orchids from all over the world. Not only are new acquisitions selected carefully based on their display quality, educational value, beauty, rarity and how they complement our present collection, but consideration is also given to how new additions will further the efforts of the NAPCC.
The Smithsonian Gardens Orchid Collection is currently well represented in New World genera such as Cattleya, Encyclia, Laelia, Brassavola, Epidendrum, Isochilus and Sobralia as well as Maxillaria, Lycaste, Oncidium, Brassia, Miltoniopsis and a wide array of Pleurothallids. Australian and Asian species of Dendrobium and Bulbophyllum are another area of specialty. Other Sarcanthine orchids include a large and varied group of Vanda and Ascocenda hybrids and a significant selection of African Angraecoids, many of which are quite rare in cultivation.
Some of the most popular plants are the collections of Cymbidium and Phalaenopsis hybrids. Their many flowered inflorescences and bright colors make for spectacular displays.

This year's exhibition will explore the rich crossroads where orchid botany, horticulture, and technology connect. Featuring orchids from the Smithsonian Gardens Orchid Collection and the United States Botanic Garden Orchid Collection, the exhibit looks at how new ideas, technologies, and inventions change the way we study, protect, and enjoy orchids. Each new innovation is like a puzzle piece: it fills in gaps in our knowledge and creates a larger and more complex picture of orchids.
