If you had to name just one tree to symbolize the South, the classic magnolia tree, aka Magnolia grandiflora would be a fine choice. Magnolia grandiflora needs a lot of space. It’s an evergreen that thrives in zones 7 to 9, often reading 60 to 80 feet in height and 30 to 50 feet across. Magnolias tolerate sun to partial shade, and open their sweetly scented blossoms in May and June.
