Step inside this glass-enclosed conservatory, and you’ll find yourself in a tropical environment filled with more than 50 butterfly species. As you walk the path through the building, butterflies flit about from flower to flower. Stand still or take a seat on one of the benches, and see if a butterfly will land on your shoulder. Plan your visit on a sunny day for the best display of butterflies, which are more active in the sunshine. Admission to the Day Butterfly Center is free with general admission to the gardens and is open year-round.
