Distribution: Southeastern United States and China.
The Tree: Silverbells are shrubs or trees with scaly reddish-brown bark. The leaves and small branches are covered with stellate (star-shaped) hairs. The showy white flowers are produced in small, pendulous clusters. They produce dry, winged fruits (drupe). Silverbells can reach a height of 100 ft (30 m), although they normally grow to 40 ft (12 m). The bark is thin, separating into slightly ridged, reddish-brown scales.
General Wood Characteristics: The wood of silverbell is brown, strong, dense and close grained. It has a wide white sapwood and a pale brown heartwood. The wood had medium luster and no odor or taste. The texture is fine and uniform, with a straight grain.
