This basic Boise wildflower field guide is designed to help the hiker or nature enthusiast identify over 80 of the most common native and non-native wildflower species found in Camel’s Back Park, Ridge to Rivers, and the surrounding Boise foothills of Southwestern Idaho.

It provides:
- Basic information about each wildflower.
