"The conservatory portion of the Como Park Zoo is worth a stop for its various gardens and exotic plants, especially on a cold winter day when you’re craving a pop of green. Start in the Sunken Garden, which hosts seasonal displays of everything from azaleas and tulips to roses and chrysanthemums, then explore the Tropical Encounters exhibition, which is home to an authentic South American rain forest filled with plants and animals. Also on-site is a palm dome, water lily pond, Japanese garden, orchid house, bonsai display, and Enchanted Garden,which attracts hundreds of butterflies every summer with its fragrant selection of plants, trees, and shrubs."
