Roger Williams Park Botanical Center is the largest indoor display garden open to the public in New England, encompassing 23,000 square feet of indoor gardens. The surrounding grounds include a rose maze, perennial display gardens, an edible forest, and much more.
The Botanical Center includes two greenhouses: The Conservatory and the Mediterranean Room. There are over 150 different species and cultivars of plants including 17 different types of palms. All the plants, with the exception of the large palm trees, were installed by park personnel. Many of the plants were saved from the old greenhouse displays and replanted, specifically most of the Cacti, Agave and Aloe. The greenhouses also display fountains, a fish pond and a small waterfall.
