Flowers in the tropics are pollinated by birds and mammals, but not in the United Kingdom. This can be something of a lottery; after all, once the pollen is carried aloft on the breeze, the plant has no control over where it will land. To create a new plant, genetic information is transmitted through seeds. In flowers that are pollinated by the wind, the pollen grains that are produced are smaller and lighter in weight, making them easier to transport by the wind.
