The southern magnolia, umbrella magnolia, and cucumber magnolia are three of the most common magnolia trees in the United States. The southern magnolia serves as the state tree of Mississippi.
The southern magnolia has a lifespan of 80 to 120 years. It usually grows 60 to 80 feet tall but can grow as high as 125 feet.
The smaller umbrella magnolia, often found in the Appalachian Mountains, has a lifespan ranging from 40 to 100 years.

Factors affecting lifespan
Magnolias can be vulnerable to ground fires, winter droughts and some insects such as the magnolia scale. Other pests and fungi can attack magnolias but are usually not fatal.
