Originally a drainage ditch, the Arboretum's Swale Garden (designed by Sandy Bayne and created in 1987) provides a tranquil buffer of attractive vegetation planted along the length of a small brook running south from a wooden footbridge to the Taylor Road entrance. Native plants, mostly shrubs, were selected for this garden to create a natural habitat, protective cover, and a travel corridor and food for wildlife. This garden features an assortment of selections including a small-leaved rhododendron, bayberry (Myrica pensylvanica), winterberry (Ilex verticillata), inkberry (Ilex glabra) and other evergreen hollies, summersweet (Clethra alnifolia), purple iris, some native shrub-dogwoods (Cornus), and several varieties of rose, including a few hardy roses added in 1995. As in other gardens at the Arboretum, invasive plant species such as yellow iris and multiflora rose have been removed purposely at various times to maintain the dominance of the natives and to prevent problems. Multi colored daylilies were added in the summer of 2012 by student volunteers along the edge of the swale by the bench for color and interest.The flowers and fruits produced in this garden provide aesthetic value throughout the year and contribute to the restful, natural character of the area.
