The giant misshapen phallus flower

Amorphophallus titanum

Amorphophallus titanum, which loosely translates as "the giant misshapen phallus", produces the world's largest flower. The flower can be over 10 feet tall at its apex. Both in its native Sumatra, and under cultivation in botanical gardens world wide, the Amorphophallus flowers only rarely, which might be good since this huge bloom also gives off a huge smell. Its odor is similar to that of a decomposing animal, which attracts the insects that help in its pollination.
