The botanical garden is located at 4101 Sherbrooke Street East, at the corner of Pie-IX and Sherbrooke Streets, in Maisonneuve Park, located in the borough of Rosemont–La Petite-Patrie, facing Montreal's Olympic Stadium. It contains a greenhouse complex full of plants from around the world, and a number of large outdoor gardens, each with a specific theme. The outdoor gardens are bare and covered with snow from about November until about April, but the greenhouses are open to visitors year round, hosting the annual Butterflies Go Free exhibit from February to April.
