Yellow pollen is produced by evergreen trees, primarily pine trees, including spruce, true cedar trees, fir trees, larch and hemlock. Although yellow pollen looks like it could cause an allergic reaction, in reality it does not trigger allergy symptoms at all. It can stain the skin and clothing, however.
The wind blows and carries the pollen for miles. Oaks are considered a primary tree for allergy sufferers. The trees produce pollen from February to late May. Oak pollen will leave a distinctive yellow smudge on cars parked near the trees during the pollen season.Although oak trees are not heavy pollen producers, they can cause real seasonal suffering for people allergic to oak pollen because the trees have such a long period of pollen production.ak pollen will leave a distinctive yellow smudge on cars parked near the trees during the pollen season.
