Some flowers smell like rotting meat because they attract pollinators that normally visit carrion, including flies and beetles. In the titan arum, dark coloration and heat can reinforce the illusion. The insects transfer pollen as they move between blooms.
A scent that targets the right pollinators
Many flowers attract bees with sweet scents, but carrion flowers use chemical odors associated with decay. Flies and beetles seeking food or egg-laying sites may approach the bloom and contact its flowers. Harvard’s Arnold Arboretum describes how the titan arum’s odor and dark inner surface attract carrion-feeding insects. [1]
Heat and color can strengthen the signal
The titan arum can warm its flowering structure and release a powerful odor when it blooms. The combination helps its scent travel and resembles parts of a carcass. The plant’s large flowering structure is not one giant flower: it is a cluster of many small flowers on a central stalk, surrounded by a leaf-like hood.
Pollination, not a trick for people
The smell evolved as a signal for insect pollinators. Human visitors notice it because our noses are sensitive to some of the same volatile compounds. The flowering episode is brief, and successful pollination depends on insects carrying pollen between plants.
Does every carrion flower smell exactly the same?
No. Different species use different blends and strengths of odor to attract their pollinators.
