Fringe Tree (Chionanthus virginicus) blooms with uniquely shaped white petals set against bright green leaves, giving off a smoky, ethereal effect. Fringe Trees do best in full sun to partial shade and need plenty of room to spread out (while they are relatively small, they do grow quite wide). Impressively, Fringe Trees can handle tough conditions like air pollution and thick soils. They are hardy in Zones 3 – 9.
