In gardens it attracts a wide range of wildlife, including caterpillars of several moths. This approach seems to work better among widely-spaced individuals. 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. Pollination is likely to be affected by a variety of environmental factors, including humidity, drought, and nitrogen deficiency.

When a flower is pollinated, the pollen grain from the male organ (anther) of the flower lands on the stigma of the female organ (pistil). Pollen grains are produced in large numbers by the anthers, whereas stamens protrude out of the flowers and are generally long and erect. The flowers are usually large and white or pale-colored so that they can be distinguished from their dark surroundings at night. Grymnosperms, such as Scots pine and juniper, are found in the coniferous forests. Instead, they rely on other parts of the plant, such as the stamen (the male reproductive organ) and pistil (the female reproductive organ), to help with pollination. When inhaled by susceptible people, these grains can cause nasty allergic reactions. The pollen of Timothy grass is a common allergen and has been used in the development of a hay fever vaccine.
