In order to improve the chances of pollination, wind-pollinated plants typically grow close together. Flowers that are pollinated by small birds usually have curved, tubular shapes; birds carry the pollen off on their heads and neck to the next flower they visit. The interactions between insect pollinators and flowers are a good example of what is known as a symbiotic relationship, in which the lives of two organisms are intimately intertwined. For example some species such as aspen dont flower very frequently, so may be overlooked. Pollen grains are very small so they blow around easily. Flies and beetles are more usually seen on open flowers, such as hogweed (Heracleum sphondylium), while longer-tongued bees and butterflies are better adapted to, and relied upon by, deeper flowers including devils-bit scabious (Succisa pratensis).

The stamen produces pollen, which is transferred to the pistil. Timothy can be confused with meadow foxtail (Alopecurus pratensis) or purple-stem cat's-tail (Phleum phleoides). An example of symbiosis can be found in the relationship between pollinators and flowers, where the lives of two creatures are entwined. When a plant is well-adapted to its environment, such as the aspen stands found in the Scottish Highlands, this strategy can be extremely effective. Fertilization occurs via an underground tube formed when pollen grains reach the styles stigma and germinate. Pollen is dispersed through catkins and cones, resulting in the production of flowers rather than energy. It is commonly grown for cattle feed and, in particular, as hay for horses.

Timothy grass is a tall, very robust perennial grass characterised by its long, cylindrical flower heads. The decline of pollinators is frequently accompanied by the absence of insect populations that are essential to the survival of the species. Unlike the typical insect-pollinated flowers, flowers adapted to pollination by wind do not produce nectar or scent. Bee flowers such as heather smell sweet and honey-like; moth-pollinated flowers, like honeysuckle (Lonicera periclymenum), are rich and heavy; and those that are pollinated by flies can be cloying and even slightly unpleasant; examples include hawthorn (Crataegus monogyna), which is carrion-like, and ivy (Hedera helix), which is also visited by wasps (Vespula vulgaris).

If the flower provides too much nectar in one go, the would-be pollen transporter may become sated too soon and will fly away without visiting another flower (although heather has a trick up its sleeve: if it is not pollinated by bees, its stamens extend so it can resort to using the wind). This approach seems to work better among widely-spaced individuals. Its main benefit is that it grows quickly and can be harvested several times in a year if planted in early spring. Hand pollination is used to improve crop yields, avoid cross-pollination, and to create hybrid crops. Bright colours, strong fragrance, bold patterns and nectar attract insects to flowers which lead to pollination. par | Juil 11, 2021 | georgetown day school acceptance rate | tom anderson cobra s review | Juil 11, 2021 | georgetown day school acceptance rate | tom anderson cobra s review Flowers in grasses, in contrast to those in other plants, are not brightly colored or fragrant in order to attract insect pollinators.
