Helianthus Annuus Pollen

Oak trees are affecting us the most right now with their pollen. You would need trees and plants mixed with dry and windy weather to have the perfect storm of pollen.

The pollen from the Helianthus annuus (the picture to the left) looks the coolest to me because it kind of look like thorns that you would find on other plants. This type of pollen also reminds me of the bacteria section we learned back in 8th grade. Helianthus annuus is commonly found in sunflowers. You can find this plant in the United States. A sunflower is a yellow flower with a brown center. This type of flower can get from 1 1/2 to 8 feet tall.
