Mulberry trees are popular ornamental and fruit trees that are native to China but are now grown in many parts of the world. Mulberry trees are not native to the United States but have been introduced and cultivated throughout the country. They are commonly found in the southern and western states, including California, Texas, Florida, and Arizona, as well as in the mid-Atlantic and northeastern regions.
Mulberry trees are dioecious, meaning they have separate male and female trees. The male mulberry trees produce pollen, which is typically released in the springtime. Mulberry pollen is small, measuring only about 15-25 micrometers in diameter. It is yellow in color and has a distinctive shape, with three furrows on its surface.
The peak Mulberry allergy season in the United States typically occurs in the spring, from late March to early May. Mulberry pollen is primarily spread by the wind, although bees and other insects may also play a role in pollination. The pollen is lightweight and can travel long distances, making it a common allergen for people living near mulberry trees. However, the exact timing and duration of the allergy season can vary depending on local weather conditions and the specific location of the trees.
It's important to note that Mulberry pollen can also cross-react with other tree pollens, such as oak and birch, which can extend the allergy season and increase the likelihood of experiencing symptoms.
