A petal is a part of a flower. Many flowers have a ring of brightly colored petals surrounding the center part of the blossom.
The very center of the flower is where its reproductive organs are located, and the petals make up its corolla, surrounding that center. The origin of petal is the Greek petalos, meaning outspread, broad, flat. Be careful when you're using the word petal not to be confused by its homophones pedal and peddle.
