The position of the nectar and the anthers are key to making sure that the insect positions itself in the right place to pick up pollen. Plants persist through the winter. Timothy has now become naturalized throughout most of the US and Canada. All release billions of pollen grains into the air so that a lucky few will hit their targets. 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. It is critical that the nectar and anthers are positioned in such a way that the insect may take up pollen in the proper location. logo Globally, the incidence of wind pollination increases with both latitude and elevation. Rosebay willowherb (Epilobium angustifolium) and foxglove (Digitalis purpurea) have blooms that open in sequence rather than all at once, reducing the possibility of insects visiting other flowers on the same plant..
