The Conservatory

Longwood's Conservatory is one of the world's great greenhouse structures. It shelters 20 indoor gardens and 5,500 types of plants. The Conservatory was built in 1919 and has been periodically expanded and renovated. At present, there are 195,668 square feet—or 4.5 acres—of covered display, production, and research greenhouses.

A leisurely stroll through the display areas takes about 1½ hours and covers about ½ mile.
