You can bring a copy of this page with you when you visit the Scenic Drive. Even better, bring a comprehensive field guide like the one mentioned below. And remember, most of the plants described here are protected by very tough and strictly enforced Arizona law.
An important source was A Field Guide to the Plants of Arizona by Anne Orth Epple published by Falcon. The plant pictures included in this section were provided by volunteers Bob Hart and Howard Myers.
