A flower has large petals, strong colour and a noticeable scent. What is the most likely reason for that combination?

توضیح

Size, colour and scent are all signals aimed at animals that can carry pollen from one flower to the next, which is why such flowers stand out at a distance and smell strongly close up. Protection is a real job in a flower, but it belongs to the small green parts outside the petals that wrap the bud before it opens.
