The Dogwood is of course an Atlanta classic and something any landscape should include. The Stellar (pink and pictured here) is a trademarked hybrid breed that is very hardy and extremely showy. 
The Chinese (white) is more disease resistant and cold hardy than the American counterpart and it blooms a little later but lasts longer than other white dogwoods.
Height/Width
Stellar about 25 feet high and wide and Chinese slightly larger.
Location
Full sun to partial shade.
Top Reasons to Plant
- Because you are in Atlanta!
- Excellent specimen tree
