This is a decent reference book, but after giving it a thorough once-over at the bookstore, I decided not to buy it, because virtually everything in the book can be accessed more readily online at sites like wildflower.org and plants.usda.gov. I much prefer Cullina's books on native plants, which have extensive guides to propagation and culture, opinionated takes on particular species, and large, beautiful photographs.
I turn to this book time and again for information on which plants would thrive in my garden. Leopold has written a clear and informative guide. I especialy like the lists in the back; e.g. "shrubs for shade", "plants that attract butterflies"
Leopold, based in Syracuse, NY, has created an excellent regional (northeast, not New England) reference for developing native plant communities in gardening and restoration. The species descriptions are divided into: ferns, grasses, wildflowers, vines, shrubs, and trees; Leopold acknowledges that both ferns and grasses could have specialty monographs for the northeast region on their own, so he lifts up only a select set of plants in each case. Excellent descriptions; lovely photography, if scale sometimes is difficult to ascertain. Highly recommended for northeastern gardeners and those interested in ecological restoration.
