Dogwood Tree Facts

Save

The dogwood family, or Cornaceae, consists of more than a dozen deciduous trees and shrubs in North America, many of which are used for ornamental purposes because of their attractive flowers. Of the dogwood trees, perhaps the most popular is the eastern-growing, flowering dogwood (Cornus florida), which some consider to be among the most spectacular native flowering trees.

Landscaping and Aesthetics

  • The flowering dogwood has two seasons of special beauty: in the spring, when it produces long-lasting white or pink flowering blooms; and in the fall, when its leaves turn a scarlet red color. It is the Missouri state tree, and its brilliant blossoms are the official state flower of North Carolina. Flowering dogwoods may grow to 40 feet high in the forest, but they usually top out at 20 to 25 feet when grown domestically. The tree's branches spread almost horizontally, often making it as wide as it is tall.

Preferred Growing Conditions

  • The flowering dogwood's preferred habitat is in filtered sunlight under the canopy of mature trees in the moist, rich soils on the edges of eastern U.S. forests. Flowering dogwoods grow in U.S. Department of Agriculture plant hardiness zones 1a through 10b. The tree thrives in nutrient-rich, somewhat acidic forest soils and sometimes suffers when planted in poorer-quality urban soil. Adding mycorrhizal fungi, fertilizers and biostimulants to the soil around an urban tree helps to correct poor soil.

Other Dogwood Species

  • The Pacific dogwood (Cornus nuttalli), with its horizontal branches and white flower clusters, is considered the West Coast version of the flowering dogwood. It grows along the West Coast in USDA zones 8a to 10b.The roughleaf dogwood (Cornus drummondii), found in USDA zones 2b through 9b, and roundleaf dogwood (Cornus rugosa), in USDA zones 2b through 7a, are shorter trees known for their flowering. The kousa dogwood (Cornus kousa), originally from Japan and Korea, is known for its four-season beauty: spring flowers, summer fruits, spectacular fall color and interesting winter silhouette. Kousa dogwood grows in USDA zones 2a through 6b.

Specialty Wood Products

  • The hard wood of dogwood trees resists splitting and denting. It is used to make weaving shuttles, spools, wood-splitting wedges, mallet heads, jeweler's blocks and golf clubs.

What's in a Name?

  • Folklore offers several theories as to how a beautiful, flowering tree got a name like dogwood. In the colonial era, the tiny fruit borne by the tree were called dog berries, which may have led to the name. Or it may have come from Europe, where the bark from a species of the tree was used in a medicine for mange. The term "dag" was once a word for a meat skewer, and the tree may have been known as a good source of dagwood.
