100 Plants to Feed the Bees

This is a book written by the Xerces Society on what native plants across North America are best for pollinators.

"The first simple step towards protecting our pollinators is to provide the flowers they need, using no pesticides.  With abundant native wildflowers, your task is even simpler: don't mow them down!  This field guide identifies the plants that honey bees and native bees - as well as butterflies, moths, and hummingbirds - find most nutritious, including flowers, trees, shrubs, herbs, and pasture plants."
