The flower of the titan arum (Amorphophallus titanium) is the largest unbranched flower in the world and can reach up to 15 feet tall. The bloom produces a smell like that of rotting meat, giving it the common name of corpse flower. A similar smell comes from Rafflesia, another plant that hails from the rain forests of Sumatra. Both plants developed their scent so they could be pollinated by flies; they don't compete with other blooms for butterflies and hummingbirds.
