The second edition of The Plants of Pennsylvania is the authoritative guide to identifying the nearly 3,400 species of flowering plants, ferns, and gymnosperms native or naturalized in the Commonwealth. It features a complete reorganization into a genetic scheme that reflects recent advances in our understanding of plant relationships.

Ralph Waldo Emerson defined a weed as a plant whose virtues have not yet been discovered. To the wild-plant enthusiast who has discovered the virtues of many plants, there are relatively few weeds. After using this book, you will never again consider lamb's-quarters a weed. Instead, you will nurture it with respect and even encourage its growth in your garden. Edible Wild Plants of Pennsylvania and Neighboring States contains botanically accurate, up-to-date information essential for the identification of more than one hundred delectable wild plants. Each plant entry provides characteristics, habitat, distribution, edible parts, food uses, precautions, and preparation, followed by tasty recipes and interesting remarks about the plant's botanical history. The plants are arranged according to height, with the ground-huggers appearing first and the trees last. Each plant is also cross-referenced by common and scientific names. The authors have written this book with the novice forager in mind, including useful tips on foraging from where to search for food to precautions to take. They also provide a list of toxic look-alikes, a nutrient composition chart, and a glossary of terms.

Authoritative, encyclopedic, lavishly illustrated guide to the trees of the state and region—from the Morris Arboretum, the official arboretum of the Commonwealth of Pennsylvania.

Three hundred million years ago, ferns dominated the earth's surface, forming extensive marshes and forests with heights of over twenty-five meters. Today, ferns and their allies are still abundantly represented in the plant world, with somewhere between 10,000 and 12,000 species identified and recognized. These nonflowering, nonseeding, highly vascular plants make up a major and ancient division in the plant kingdom called Pteridophytes. In the state of Pennsylvania, one can find more than 100 species of these highly specialized plants. While ferns are by far the largest division of the Pteridophyte group in the state, horsetails, clubmosses, spikemosses, and quillworts are the lesser-known members, frequently misidentified as relatives of more modern flowering plants. With more than 190 color photographs and descriptions of 96 different plants, recognizing each Pteridophyte is a relatively easy matter. The photos of the plants show them growing in their natural settings, which helps to establish a clearer picture of the common characteristics of the families and their likely habitats. Maps illustrate the distribution of the various species throughout the counties of Pennsylvania and across the United States. Taxonomic keys are also included for each of the groups to assist in identifying the plants based on their biology. Finally, the book provides the most common local names for the plants, making it useful for both the amateur naturalist and the professional botanist.

A comprehensive reference and discussion about how to plan and develop landscape designs using native plants, with a focus on the northeastern counties of Pennsylvania. Covers 2,150 species of trees, shrubs and herbaceous perennials and annuals, 100 kinds of regional soils, and 135 ecological communities with detailed plant associations for each. Also included are the 540 protected plant species in Pennsylvania, invasive species of local concern, plant sources and additional resources for native plant enthusiasts.

Common and uncommon tree species described in engaging detail. Covers trees found in small woodlots, deep forests, backyards, and reverting fields.

From the Delaware River to the shores of Lake Erie, Pennsylvania's diverse watery habitats are home to more than 200 species of aquatic plants. In Aquatic Plants of Pennsylvania: A Complete Reference Guide, botanists Timothy A. Block and Ann Fowler Rhoads have assembled the first identification guide specific to the Keystone State yet useful throughout the Mid Atlantic region. Organized and written in a way that will make information easily accessible to specialists and nonspecialists alike, the book highlights the diversity and vital ecological importance of this group of plants, providing photographs, illustrations, descriptions, and identification keys for all emergent, floating-leaved, and submergent aquatic plants found in the Commonwealth. An introductory chapter on aquatic plant ecology covers topics such as evolution, form, and reproduction of aquatic plants, vegetation zones, types of aquatic ecosystems, and rare and endangered species. Information on invasive plants, such as Eurasian water-milfoil and curly pondweed, that threaten Pennsylvania's aquatic ecosystems will be especially useful to watershed organizations, citizen monitoring projects, lake managers, and natural resource agency personnel. An illustrated identification key guides the reader through a series of steps to properly identify a specimen based on its characteristics. Each of the more than 200 listings provides a plant's taxonomy, detailed description, distribution map, and expert botanical illustrations. Many also include color photographs of the plants in their natural habitats.
