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 yellow color of zucchini blossoms attract bees necessary for pollination. Zucchinis (Curcubita pepo) are botanically related to cucumbers, squash and melons. All plants need male pollen added to female flowers in order to bear fruit. Some plants have flowers with both sexes, while others, like zucchinis, have separate male and female flowers. The striking yellow color of zucchini flowers attracts bees that carry the pollen from male to female parts. Zucchinis are warm season vegetables that mature in 35 to 55 days.
