Wet, poorly drained soils present one the most difficult challenges for growing plants in the landscape. Excessive moisture displaces oxygen in the soil and plant roots can suffocate as a result. Many plants are intolerant of having their roots submerged for extended periods of time. Even though standing water may not be present, poor drainage is often responsible for reduced growth and survival of plants in our landscapes.
Two hydrangea species are native to the southeastern United States -- Hydrangea arborescens and Hydrangea quercifolia. Both are bold-textured, deciduous shrubs which produce small, fertile flowers. Many selections are considered more garden-worthy than the native species because they display large, sterile florets.
Boxwoods have been an important part of North Carolina landscapes since colonial times; the first plants were introduced to American gardeners in 1652. Boxwoods are suitable for formal and informal landscape use as edging, hedge, screen, accent, and specimen plants. While boxwoods are considered an essential component of historical and colonial gardens, they can also be used in traditional and contemporary landscape designs.
This leaflet includes a list of recommended trees that have demonstrated particular resistance to harsh growing conditions, diseases, and insects in North Carolina. It should be emphasized, however, that even these trees have their limits. No single species is suited for all sites and consideration should be given to soil conditions, local occurrence of diseases and insects, microclimate, hardiness zone, and mature tree size when selecting any plant.
Selecting trees for use under utility lines presents a unique challenge. It is often desirable to have trees that are large enough to provide shade, architectural effects, and ornamental features, all without interfering with overhead utility lines. In this publication, we have listed trees that have a typical mature height of less than 30 feet.
