5 Interesting Facts About Cedar Fever

Cedar Fever

Think you know everything about the infamous mountain cedar tree that’s a common sight in central Texas? Here are some facts about this allergy-inducing plant that might surprise you.

Fact: Cedar fever isn’t caused by a cedar tree.

Cedar fever is a seasonal allergy caused by an allergic reaction to pollen from a tree known as mountain cedar. Despite its common name, the mountain cedar actually belongs to the juniper family! The scientific name for mountain cedar is Juniperus ashei. There are around 70 species of evergreen trees and shrubs in the juniper family, many of which are called “cedars.”

Fact: Cedar fever doesn’t produce a fever.

Ironically, cedar fever does not actually produce a fever. The immune system of a person with a cedar allergy mistakes the pollen as a harmful substance and induces a reaction. Cedar fever symptoms may include itchy, watery, red eyes; sinus pressure, nasal congestion and runny nose; sneezing; sore throat and fatigue. 

Fact: Cedar fever only affects certain parts of the country.

Only about 100 of the more than 50,000 species of trees cause allergies. Because mountain cedar trees are limited to Arkansas, Missouri, Oklahoma and Texas, residents of these states are primarily affected by cedar fever. Texas has the largest stands of trees, making Texans far more likely to suffer from the allergy.

Fact: Only male cedar trees produce pollen.

Beginning around December, male mountain cedar trees distribute pollen from small, amber-colored cones at the top the tree. A female mountain cedar tree produces berries containing seeds, but no pollen. 

Fact: Cedar pollen can be distributed miles away from the original source.

Mountain cedar trees generate some of the highest concentrations of pollen of any plant. Huge clouds of cedar pollen have been observed to travel more than 100 miles on dry, windy days.
