nectar
Flowers attract insects by: Big and colourful petals. Sweet scented. By nectar.
Different smells attract different people. If a woman or a man wears fragrance, they are more likely to attract a member of the opposite sex. Other smells that attract people can include food, the smell of the seashore, or flowers.
Some flowers, such as the corpse flower, emit smells that resemble rotten meat to attract specific pollinators like carrion beetles and flies. These pollinators are drawn to the scent as they feed on decaying matter and help to transfer pollen between flowers, aiding in reproduction. This adaptation allows these flowers to maximize their chances of successful pollination.
Flowers that smell like rotting meat rely on carrion flies for pollination. They pollinate as it normally does but instead of pollinators or insects to help it pollinate, other resources like wind, help the pollen get around easily due to is light weight
Color, shape, odor, and taste. For example, honeybees are attracted to bright colors, open-petal-shaped flowers, flowers which have certain smells, and the sweet nectar produced by many flowers. They can even be "trained" to pollinate flowers which humans might not find particularly attractive such as onion (allium spp.) flowers.
fresh air and flowers
The tree requires to attract pollinators to the flowers before the fruit can form. The flowers on the plants on the ground can be pollinated by passing animals moving their pollen around.
but smells like flowers
Pollinators such as bees, butterflies and other insects or birds are attracted to the colors and smells of certain flowers. During the feeding process cross pollination occurs.
Many flowers, like the hibiscus have evolved to attract insects by traits such as bright colors and attractive smells.
The smells in flowers come from special oils that are produced in the petals as the plant grows. When this oil evaporates, which it does very easily, it gives off a fragrance which we can smell. Various combinations of chemicals in the oils of different flowers result in a variety of fragrances. Some are pleasant, sweet smells, like those of roses, lilacs, and lilies, while others are quite unpleasant. The pelican flower of South America, for example, smells like rotten meat! Flowers get their red, purple, orange, pink, or yellow colors from the pigments, or coloring matter, in the sap of their cells. It is both the scents and colors which attract insects and birds, which land on the flower to sip its nectar. In doing so, they help to spread the pollen for new flowers. Many flowers have the same oil in their leaves, roots, and fruit as they have in their petals, so we can smell the fragrances in those places too!
