The studies I've read indicate that plants provide minimal help in reducing noise levels. However, any noise reduction is welcomed, and the visual barrier the plants provide is usually preferred to that of vehicles on a busy street. I would try to layer dense evergreens in an attempt to muffle noise. A row of evergreen trees along the property line might help. These mature to about 30 feet and are certainly attractive.
Female plants produce berries.
Plant so that mature trees are touching for the best screen. Leyland cypresses are naturally pyramidal in shape, with a mature height of about 30 feet. Large evergreen shrubs could add another layer. Oleanders, Southern wax myrtles and elaeagnus, a drought-tolerant, vigorous shrub with silvery foliage, are alternatives. A tall brick fence might help but may not be an option.
