People value flowers not only for their beautiful shapes and colors but also for their scents. Not all species of flowers have such an intensive scent that people are able to smell it – some of them seem to be odorless for human beings, however, bees and other insects can smell them perfectly well. It is interesting that the scent of flowers changes not only during the whole cycle of their blossom but it also differs at various parts of a day. It is associated with the activity of insects that pollinate them – flowers give off a special scent in order to “attract” them.
