Pollen Allergy Trees and Plants 

There are hundreds of plant species that release pollen into the air and trigger allergic reactions. Here are the different types of common trees and plants that produce pollen allergies, especially in the United States.

Birch Pollen Allergy

Birch Tree Pollen Allergy

Birch pollen is one of the most common airborne allergens during the spring of all pollen allergy trees and plants. As the trees bloom, they release tiny grains of pollen that are scattered by the wind. A single birch tree can produce up to five million pollen grains, with many traveling distances of up to 100 yards from the parent tree.

Oak Pollen Allergy

Like birch trees, oak trees send pollen into the air during the spring. While oak pollen is considered to be mildly allergenic compared to the pollen of other trees, it stays in the air for longer periods of time. This can cause severe allergic reactions in some people with pollen allergies.

Grass Pollen Allergy

Grass is the primary trigger of pollen allergies during the summer months. It causes some of the most severe and difficult-to-treat symptoms. However, a recent study published in The Journal of Allergy and Clinical Immunology found a grass allergy immunotherapy medication to be highly effective in relieving symptoms when other treatments have proven ineffective.

Ragweed Pollen Allergy

Ragweed plants are the main culprits of allergies among weed pollens. They are the most active between the late spring and fall months. Depending on the location, however, ragweed may begin spreading its pollen as early as the last week of July and continue into the middle of October. Its wind-driven pollen can travel hundreds of miles and survive through a mild winter.
