Low Water Use Plants

ADWR Regulatory Plant Lists are used to regulate public medians and rights-of-way in Arizona’s five Active Management Areas (AMAs). Jurisdictions within many AMAs officially adopt the local ADWR list and incorporate it into ordinances and design guidelines for development. The lists also serve as a non-regulatory resource for residents. The lists were developed independently with the assistance of plant experts from each AMA.
