Site of four old greenhouses, the Roger Williams Park Botanical Center opened in March. With a 45-foot-high conservatory and greenhouses stretching over 12,000 square feet, the complex is New England’s largest public indoor display garden. ‘‘The woman who did the design really thought about the diverse population in Providence,’’ said Alix Ogden, Providence Parks superintendent, ‘‘so people have a personal connection to it.’’ Amid the palms, bananas, lemon trees, carnivorous plants, cacti, and vanilla orchids, visitors from the Caribbean and South and Central America should feel right at home. For others, as the green fades outside, the center provides a welcome infusion of heat, steam, and chlorophyll.
