A reduction of native insects means that birds have fewer insects to feed to their young, and that will lead to a reduction of bird species. The insects rely on native plant hosts and cannot eat the exotic plants that have become common in our yards. Doug Tallamy of the University of Delaware has determined that 90 percent of our native insects are specialists that feed on three or fewer families of plants. Development is rapidly reducing natural areas that shelter a wealth of our native plants the landscapes that replace the natural areas consist mostly of lawns and exotic plants. Perhaps the most compelling reason to choose natives is to preserve Pennsylvania's biodiversity. Many native perennials like less fertile soil and require the addition of little or no fertilizer. Because they evolved here, they are well-adapted to our climate and are generally easy to care for once they are established. Why Natives?īy definition, a native Pennsylvania plant is one that grew in Pennsylvania before the European settlers arrived, as opposed to exotic plants which came from other countries after that time period. Though thousands of perennials are available, native perennials have a special role in the garden. Herbaceous (non-woody) perennial plants add year-round interest to any landscape and are a popular choice of plants among gardeners. ![]()
