There are much better books on buttrerfly gardening out there than this one - I recommend Butterfly Gardening by the Xerces Society. Its got not only the plants that butterflies like but also the lifecycle of butterflies. Creating A Butterfly Garden is like the hummingbird gardening book by the same author - very very basic with listings of plants and drawings of gardens but little more. You can get what's offered in these books off the internet. I ended up spending a little more to get a decent book that got me further below the surface and have a great butterfly garden going - variety is the key. The more kinds of flowers, the more kinds of butterflies. Its important to recognize that to have butterflies you need to have caterpillars too and they are fun to provide for and watch develop as well
