Smithsonian greenhouses in Suitland, Maryland (Smithsonian Gardens)

Discover what it takes to keep the Smithsonian’s many gardens and interior plant displays looking their best all year round. Smithsonian horticulturist Vickie Dibella takes you on a behind-the-scenes tour of the Smithsonian Gardens’ Greenhouse Nursery Operations facility in Suitland, Maryland, whose greenhouses provide plants for the institution’s gardens and horticultural exhibits.

Learn how staff care for the acres of annual bedding plants destined for the Smithsonian’s gardens, as well as the huge tropical specimens that hibernate for the winter at the greenhouses. The 10-acre facility includes growing areas, exterior storage, and greenhouses devoted to tropical plants, interior display plants, and nectar plants used for the Butterfly Pavilion at the National Museum of Natural History.

Get a close-up look at the thousands of plants that make up the Smithsonian Orchid Collection, which delight your senses with their fragrances, colors, sizes, and shapes. Find out about the environmental control systems needed to nurture the many plants in the Smithsonian Gardens system and get a preview of the blooms and plants that will add their color to the Smithsonian’s spring displays.
