Untitled design (16) (1)Juniper is an evergreen coniferous shrub or small tree found at higher elevations throughout Arizona.  Most common are the  Alligator Juniper (named because of it’s distinctive rough bark) and Oneseed Juniper.  Both produce allergenic pollen during winter through early spring, and although these trees are not common in the desert regions, the pollen finds it’s way into the valley  in sufficient quantity to cause significant symptoms in sensitive individuals.  Several ornamental varieties of Juniper and Cedar are used in landscapes in the valley.   Because the pollen of most varieties of Juniper and Cedar are closely related, if you are allergic to one, you will have problems with all.
