The Southern Magnolia (Magnolia grandiflora) is grown for its intoxicating and showy white flowers and handsome, glossy evergreen foliage. It is a large, stately evergreen tree that is useful in defining the edges of larger landscapes and can be used as a specimen. The large, leathery leaves are slow to decompose and it is hard to grow other plants underneath Southern Magnolias. Plants are drought tolerant once established but trees growing in urban environments where they get reflected heat from pavement or buildings may require supplemental water.
