Which Dogwood?

Hiking along a park I came across this dogwood growing along the side of the woods under taller trees. I have always had trouble deciding between Roughleaf and Gray dogwoods. So I decided to compare the 2 with my books.

What is the difference between Gray Dogwood and Roughleaf Dogwood?

• Roughleaf dogwood has white flowers, while Gray Dogwood has red flowers.
• Roughleaf has red/brown older twigs, while Gray dogwood has gray twigs that are older.
• Gray dogwood has tight bark that is roughed by lenticles.
• The young twigs on Roughleaf are hairy while the Gray dogwoods are not.

So this one is Roughleaf dogwood.
