  Previous topic Next topic JavaScript is required for the print function  

The genus Cornus contains about 40 species which grow in the northern temperate regions of the world. The name cornus is derived from the Latin name of the type species Cornus mas L., Cornelian-cherry of Europe, from the word for horn (cornu), referring to the hardness of the wood.

The following description is for flowering dogwood.

Distribution: North America, from Maine to New York, Ontario, Michigan, Illinois and Missouri south to Kansas, Oklahoma, and Texas east to Florida.

The Tree: Flowering dogwood is well known for its white flower clusters with large white bracts opening in the spring. The fall foliage is bright red. It is a slow-growing tree which attains a height of 40 ft (12 m) and a diameter of 16 inches (40 cm). The bark looks like reddish-brown alligator skin. The tree grows best along streams and in well-drained soils.

General Wood Characteristics: The sapwood of dogwood is wide and creamy in color, while the heartwood is reddish brown to brown, sometimes streaked in white. The wood has a fine, uniform texture with a hard, compact interlocked grain. Strength is similar to that of European Beech, but higher in hardness and shock resistance and slightly lower in stiffness.
