Importance of Flowers in Nature

Pansies have many uses.

Flowers' importance in nature is everywhere—they can feed insects, birds, animals and humans; provide natural medicines for humans and some animals; and aid in a plant’s reproduction by enticing outside pollinators. Without flowers, plants would merely be green, and the world would be a duller place.

Reproductive Aids

Flower stamens aid in reproduction.

The main purpose of flowers is to aid in plant reproduction. Flowers provide an eye-catching attribute to an otherwise plain, green-leaved plant. When insects, birds and some bats dip down to take a look at the flower and steal its nectar, they are inadvertently pollinating the plants by moving pollen or plant sperm from the male stamens to the female pistils.

Nectar for Insects, Birds and Bats

There are a variety of insects that feast on the nectar of flowers, but the most notable ones are bees, wasps, ants and butterflies. Because these flowers rely on an outward source to pollinate them, some plants have evolved to make themselves even more attractive to their pollinators.

The bee orchid has even evolved so that it appears as if a female bee is on the orchid, when in fact the "bee" is actually part of the flower. The hibiscus and trumpet vine flowers have evolved so that their nectar can be easily taken and their pollen easily transmitted by hummingbirds and sunbirds.

Nectar and pollen-eating bats feed on flowers from agave, organ pipe, cardon and saguaro. According to Katy Hinman, a graduate student at State University of New York-Stony Brook, these plants have evolved to only open their flowers at night, thus releasing their nectar and pollen when it is convenient for bats.

Food Source for Humans

Chives taste great in a variety of dishes.

Rose petals have been used in cooking and teas for centuries, as have day lilies, dandelions, carnations, clovers and daisies. Citrus and banana flowers can also be a food source. The blossoms from chives, garlic, basil, jasmine, lavender, oregano and sage can be used as herbs and spices in food dishes. Other flowers, such as mint, chamomile, ginger and Angelica, can be used in teas.

Food Source for Animals

Some animals love geraniums.

Deer and rabbits are the biggest flower predators in the animal kingdom. Geraniums and pansies are the first to be eaten, as are flowering vegetables. Raccoons, skunks and groundhogs also nibble on flowers from time to time.

Medicinal Aids

Begonias can be used for medicinal purposes.

Many flowers have medicinal uses, such as begonia for eliminating toxins in the body, and calendula, sunflower and honeysuckle for treating sore throats and tonsillitis. Cornflower can be used to treat acne, while valerian and California poppy relieve menstrual cramps. Cats even use flowers to cause vomiting and thus eliminate stomach distress.
