Pollination by the wind is very hit and miss. The wind may pick up pollen from a grass flower and scatter it all over the place. Only by chance will a little pollen land on another flower of the same species.
To make up for this waste, wind-pollinated flowers produce a huge amount of pollen, as hay fever sufferers will know. Wind-pollinated flowers tend to have small dull-coloured petals or, in the case of grasses, no petals at all.
The pollen grains are not sticky like those of animal-pollinated flowers, which reduces the chance of them sticking to leaves and other obstacles. The stigmas of receiving flowers are sticky in order to hold on to pollen carried by passing breezes.

Flowering plants have several different parts that are important in pollination. Flowers have male parts called stamens that produce a sticky powder called pollen. Flowers also have a female part called the pistil.
The top of the pistil is called the stigma, and is often sticky. Seeds are made at the base of the pistil, in the ovule. To be pollinated, pollen must be moved from a stamen to the stigma. When pollen from a plant's stamen is transferred to that same plant's stigma, it is called self-pollination.
When pollen from a plant's stamen is transferred to a different plant's stigma, it is called cross-pollination. Cross-pollination produces stronger plants. The plants must be of the same species. For example, only pollen from a daisy can pollinate another daisy. What is Pollination? Celebrating Wildflowers. Why is Pollination Important? Why Use Native Plant Materials?
