Create Space, and Amazon.com right now, as well as the Kindle Bookstore. The emphasis is on Eastern Natives Plants, though not quite as south as Florida, Texas, or California. I know it's not really said anywhere but hopefully the big New England Aster on the cover gives everyone the idea. A few western natives are included but not many, and certainly not as many as I'd like to recommend.
A Brief Overall:
Is it Native?
The Evolution of Flowering Plants: How different flower shapes attract different pollinators. Some native bees will only use the pollen to certain plants to feed to their young, in a similar way that butterflies only lay their eggs on certain host plants.
Measuring Biodiversity: Butterfly Gardening, some of the other insects native plants attract, Leaf Beetles, Aphids, and their predators and parasites and such.
Ants: they make up 1/3 the total insects of the world by number (not species) so it only makes sense to talk about their relation with honeybees. Honeybee hives are often used by some species as nests, and the hives themselves are fountains of resources in many regards. I talk about the degrees in which ants interact with them. The topic of illegal trade is also brought up here.
Don't Waste Their Time: This is the best advise I can give to any gardener trying to get honeybees in their garden.
The Plant List: 95 pages of Food Plants, Flowering Trees, Spring Ephemerals, and Wildflowers honeybees use to get them through the year. Not all are commercially available but those that aren't are brought up for good reason. Most are available of course.
Book Recomendations and Native Plant Nurseries with emphasis on ones that allow you to fill up a shopping card and check out on your own. I hate nurseries that call you in person and ask for your credit info.
