Pests and Diseases
There are a number of fungi that attack the southern magnolia, including species of Cladosporium, Colletotrichum and Septoria that cause leaf spots but these seldom result in any significant damage. Heavy infestations of magnolia scale can kill branches or entire trees. A variety of other pests including tuliptree aphid, striped mealybug and spider mite feed on the magnolia.

Of Note
Magnolia grandiflora is the state tree of Mississippi and the state flower of Mississippi and Louisiana.

In many urban areas where other species do poorly, this magnolia can grow because of its resistance to damage from sulfur dioxide.

President Andrew Jackson planted a southern magnolia on the White House grounds that stands to this day.
