Plants appeal to the senses - visitors of all ages are captivated by the sights, smells, sounds and textures that surround them in our Conservatory.

The U.S. Botanic Garden is a museum with a difference. Our artifacts are the living treasures of the plant world. The towering leaves, graceful flowers, delicate seeds and exotic fruits of plants at their peak are displayed artfully throughout the historic Conservatory.

You will find a world of plants and environments in our permanent exhibits and gardens:

  • Garden Court: The colorful foliage and flowers create a beautiful setting to feature economic and ethno-botanical plants used in products that provide our fibers, food, beverages, cosmetics, wood, species and more.
