Pollen is in the air, is that correct?

Where and when does pollen exist?
To quote Wikipedia, "Generally pollens that cause allergies are those of anemophilous plants (pollen is dispersed by air currents.) Such plants produce large quantities of lightweight pollen (because wind dispersal is random and the likelihood of one pollen grain landing on another flower is small) which can be carried for great distances and are easily inhaled, bringing it into contact with the sensitive nasal passages.





In the US, people often mistakenly blame the conspicuous goldenrod flower for allergies. Since this plant is entomophilous (its pollen is dispersed by animals), its heavy, sticky pollen does not become independently airborne."





Pollen that causes allergies are generally grasses, weeds, trees not flowers. That does not mean you can not be allergic to flowers but chances are it is not the pollen of the flower. Pollen is produced at different times of the year depending on what the pollen is and where you are located.
Reply:pollen is from flowers. and flowers grow in the spring time, which is why that is when allergies are the worst! pollen helps flowers grow and i guess when the wind blows, it gets into the air
Reply:Yes, polen is in the air. Polen are reproductive spores that float through the air %26amp;/or are carried by insects %26amp; animals. Pollen does not just come from flowers. Many plants use pollen to reproduce %26amp; it happens throughout the year. I'm sensitive to a particular tree pollen here in Denver so my allergies tend to act up in late winter/very early spring. However, during wet summers my allergies can act up all summer long. So it's not just WHEN but WHAT TYPE of pollen you are allergic too.
