Conifer seeds are produced in tiny scale-like things called seed cones or ovulate cones. These are completely different from the yellow, wormlike, pollen-producing cones you shook next to your car. At pollination time, seed cones are so small and inconspicuous that most people never notice them.
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.
