List of Arizona Allergens

Arizona, with its desert climate, has its own collection of allergens. Although people might assume a dry climate such as Arizona's would be beneficial for allergy and asthma sufferers, it is important to remember that varying conditions may prevent new problems. The following is a list of common allergies for residents and visitors within the state of Arizona.

Bermuda Grass

• During June through September, Bermuda grass is a common allergen. It is one of the top two offenders for allergy sufferers in the Arizona area. It produces twice as much pollen per day as other plants, according to the Arizona Cooperative Extension. It also flowers several times during the season, causing extra issues for allergy sufferers. Cynodon dactylon is the scientific name of Bermuda grass.

Fruitless Mulberry

• Another aggravator within the Arizona area is the fruitless mulberry. Its scientific name is Morus alba. Although once believed to cause few allergic reactions, the opposite is now true. This plant flowers February through March, the Arizona Cooperative Extension says. This tree is popular in landscaping and was introduced to the Arizona area from another climate. The combination of native and non-native plants may be one reason Arizona is no longer a hideaway for the allergy sufferer.

Hackberry

• Hackberry, also known as celtis occidentalis, is another offender on the Arizona allergy scene. Hackberry is a deciduous tree that causes many problems for allergy sufferers. It causes most of its issues from February through March. In some parts of the state, it may be problematic into the month of June.
