The flowering dogwood tree grows approximately 16 inches per year, which puts the average height of a 10-year-old dogwood at 16 feet. At full maturity, a dogwood tree is approximately 33 feet tall. The trunk of a mature dogwood reaches 1 foot in diameter.
Dogwood trees typically grow wider than they do tall. A tree planted in a wooded area can be expected to grow faster and larger than a tree planted by itself in a yard. Dogwood trees thrive in moist, acidic soil with afternoon shade and morning sun. The flowering dogwood is the most common type of dogwood tree.
