A sure sign that winter is gone and that spring and summer are on their way is flowers. Who doesn’t enjoy the beautiful colors and fragrances of flowers? However, flowers serve useful purposes, also.
What is the purpose of a flower?
Flowers are the reproductive part of plants. It is the flower that produces seeds which then grow into new plants. So the first function of flowers is to help reproduce new plants.
To reproduce a new plant, pollen from one flower must be carried to another flower. Each flower has a specific design which best encourages the transfer of its pollen. Some kinds of flowers attract and use insects, bats, birds or other animals to transfer pollen from one flower to the next. These flowers tend to be brightly colored or have other special features that attract the insects and animals. Other kinds of flowers use the wind to move pollen from one flower to another. These plants, such as grasses and many trees, don’t need fancy flowers to attract animals. So their flowers are often small and without much color.
Have you ever eaten a flower?
Flowers usually smell and look good, but how do they taste? Some flowers can be used for food and drink. Broccoli, cauliflower, and artichokes are flower vegetables. Many spices and herbal teas come from flowers. Some flowers such as squash blossoms can be eaten fried or added fresh to salads.
Flowers can be weird!
Flowers come in the widest variety of colors imaginable and in a wide variety of sizes, too. The wolffia angusta is the world’s smallest flower. If you take the “o” out of “flower,” you can put two wolffia angusta plants inside the “o.” A dozen of these dainty flowers can sit on the head of a pin with no trouble.
At the other extreme is the rafflesia arnoldii. This giant produces the largest individual flower on earth. You’ll have to travel to the rainforests of Sumatra and Borneo in the Indonesia Archipelago to catch a glimpse of it. The bud takes many months to develop and bloom into a flower. Once Rafflesia arnoldii blossoms, it shouldn’t be hard to spot. This flower can grow to a diameter of nearly a meter and can weigh up to 11 kilograms. It has a fleshy color with reddish spots. No one will seek rafflesia arnoldii for its fragrance. It smells terrible! And it has a few other odd characteristics, as well. There is a hole in the center of the blossom that holds about six liters of water, and the plant has no leaves, stems, or roots.
