Some are no bigger than your thumbnail, while others are the size of your hand. Some mimic bees and butterflies, while others resemble a lady's slipper. Orchids can be found in Africa, Asia, the Caribbean, and the Americas, and have evolved to survive in astonishing places. Orchids truly are the seductive stars of the Garden's tropical plant collections, and can be viewed year-round in changing displays in the Conservatory and the Orchid Rotunda in the Library Building.

Marvel at rare orchids growing as they would in nature in the Conservatory's rain forest galleries. Celebrate their spectacular beauty and diversity with the annual Orchid Show beginning in February, where thousands of orchids fill a lush tropical landscape.

From blue Vanda orchids and Vanilla planifolia orchid to tiny Pleurothallis and Macodes, the beautiful and spectacular members of the orchid family can always be found on display in the Conservatory.

Orchids take center stage each spring in the Conservatory during the annual Orchid Show.

Paphiopedilum is known as ladies’ slipper orchid because of its resemblance to a tiny shoe. Charles Darwin correctly predicted that the unusual orchid that now bears his name had evolved along with a unique pollinator. And one particular cultivar of Oncidium bears the distinct scent of chocolate.

Even as the days grow shorter and colder, visitors can still be transported to warmer climates by the displays of orchids and other tropical plants in the Conservatory and the Orchid Rotunda.
