alike are beginning to appreciate the environmental, economic and aesthetic benefits of natural landscaping,” according to the US Environmental Protection Agency.6 Horticulturists and naturalists provide an explanation for this trend: “Today, there is renewed interest in ‘going native’ and restoring diversity to our landscapes by choosing native plants. The reasons for this are many and varied. Planting a native plant provides habitat for a variety of native wildlife species such as songbirds and butterflies. Including native species provides a historical sense of pride to a gardener who grows a plant that Native Americans or early pioneers valued. Furthermore, regionally-adapted native plants have developed a natural resistance to regional pests, and a tolerance to drought, ice storms and other environmental extremes common to the area.”7 Midwesterners with questions about native plants can readily find answers. Typing words like “native plant” into an Internet browser produces helpful information. Organizations and books devoted to birds, butterflies, pollinators, gardening with native plants, native plant nursery catalogs, and our own observations provide information and inspiration to advance the trend toward “natural landscaping.” For more information, please see Selected Bibliography and Resources.

      “Now is the time to get started because time is not on our side as more of our native habitats disappear.”8 Regardless of the location or the size of our property, native plants create habitats and migration corridors for wildlife. Even small urban patches can be lifesavers for pollinators (butterflies, moths, bees, beetles, bats, ruby-throated hummingbirds), insect-eating migrating warblers, and other birds that fly from place to place.9 Plantings of thoughtfully chosen and responsibly cared-for native woody and herbaceous species help prevent harm and ensure maximum benefits.

      “Planting natives in small landscapes will not recreate ancient ecosystems, but it does create biodiversity to support what’s left of our wildlife,” states Douglas Tallamy, who suggests keeping lawn for where we walk or use it for recreation. “The rest of the landscape would consist of bunching grasses, shrubs, understory trees and canopy trees.”10 Simply by replacing portions of our lawns with native trees, shrubs, and herbaceous species, we can greatly improve home and neighborhood ecosystems.11 Sharing information about the importance of natives and how to choose and purchase them helps create change. Whether by small incremental steps or by big landscaping projects, each of us can decide to help ensure a future for butterflies and birds by choosing life-giving native shrubs and trees.

      Homeowners, gardeners, and landscapers have the ability and opportunity to make good environmental choices and to create beautiful landscapes and gardens. And that is something to celebrate. We wrote this book to bring wider attention to the age-old connection between native woody plants and native wildlife. We hope the information we share will intrigue and inspire readers to protect this delicate balance by emphasizing native midwestern woody plants when landscaping and gardening.

      HOW TO USE THIS BOOK

      MIDWESTERN GARDENING and landscaping take into account the changing seasons, so we present our book on woody species in sections entitled Spring, Summer, Fall, and Winter. Spring focuses on spring flowers. Summer looks at summer flowers and shade. Fall features leaf color. In winter, bark, decorative shapes, and evergreens become the focus. Each season is subdivided into shrubs and trees (species sometimes overlap) and contains a selection of alphabetically listed (in red) nonnative (introduced, alien, exotic) woody plants that are popular in the Midwest (each followed by one or more native species, listed in green). For maximum accessibility, we list the plants by their common names. Later references to the plant use only the first common name listed. Following a plant’s common name or names, we list its family, genus, and, in parentheses, species. When we repeat the genus name, it is abbreviated, as in this example: H. cinerea instead of Hydrangea cinerea. We provide the nonnative plant’s origin (not shown in USDA PLANTS), frequently Asia or Europe. Next we present the plant’s height, notable ornamental features (flowers, fruit, fall color), and cultivation requirements. We provide Ecological Threat notes, based on USDA PLANTS maps designating nonnative plants naturalized in the Midwest (eastern half of the United States). USDA PLANTS maps reveal the great extent to which nonnative woody and herbaceous species have moved into our midwestern ecosystems. Using “I” for “Introduced” and defining the term as “naturalized,” USDA PLANTS states, “In general, introduced plants are likely to invade or become noxious since they lack co-evolved competitors and natural enemies to control their populations.”1 No single clear controlling entity defines the term invasive, or designates a species as being invasive or not. To determine if a nonnative plant is invasive, we relied on data from a variety of invasive plant organizations and governmental resources that evaluate plant species for invasiveness.
