Titan arum (Amorphophallus titanum), blooming at the Conservatory of Flowers in Golden Gate Park, San Francisco, California. Native to Sumatra, it is also known as the corpse flower because of its putrid smell, which attracts insect pollinators. The 'flower' is actually a cluster of hundreds of smaller flowers which together reach a height of up to nine feet, making it the largest reproductive organ of any plant in the world.
