The Smithsonian’s National Museum of Natural History has just opened the exhibit Butterflies + Plants: Partners in Evolution which features an interior Butterfly Pavilion. The Pavilion showcases multiple species of tropical butterflies as well as over 250 nectar and pollen producing plants in an enclosed climate-controlled setting.

The Horticulture Services Division supplies and cares for the plants exhibited in the 500 square feet of planting display space and assures that they are grown in a pesticide-free environment. Over 100 plants are rotated into the Pavilion several times a week in order to provide a constant source of fresh nectar and pollen for the butterflies. When necessary, spent plants are disposed of in accordance with USDA requirements.

The varieties of flowering plants highlighted in the Butterfly Pavilion will change throughout the year depending on seasonal availability.
