|ALLERGY AND ASTHMA IN THE SOUTHWESTERN UNITED
Recommended Plants for Homes of Allergic People in Maricopa and Pima Counties
The plants listed below have been selected for their low production of airborne pollen, as well as utility in landscaping and availability in plant nurseries. This is only a partial list of suitable plants. Many species closely related to those on the list are also available from local nurseries and could be used. The plants listed are low water use or drought tolerant, selected from the list published by the Arizona Department of Water Resources. Pictures of most of the plants can be found in "Plants for Dry Climates" by Mary Rose Duffield and Warren Jones, H.P. Books, Fisher Publishing, Tucson, September 2001. Photos of many of these plants can also be seen on the USDA Plants site, the Phoenix Tropical Gardens site.
Not shown on the list are high water use, low allergy plants such as deciduous fruit trees, most roses and many other brightly colored flowers, none of which produce large amounts of airborne pollen. Identification of female trees may be impossible unless purchased as large specimens during their flowering season.
