Conservatory of Flowers
Time Out says
This is the oldest public wood and glass conservatory on the continent, housed in an ornate Victorian building that has withstood earthquakes and fires aplenty. The dome is teeming with vibrant, otherworldly flowers, including aquatic and tropical plants from Brazil, China, Ethiopia, Ecuador and beyond. The conservatory is best known for its assortment of jaw-dropping orchids, as well as fanged carnivorous plants and Monet-worthy water lilies.
