Fragrant 8" white flowers in summer are outstanding on this magnificent specimen tree (to 90'); glossy leaves and pods with red fruits. S/M
The Giant Evergreen Magnolia is by far one of the most interesting Magnolia species, it produces massive white flowers that are lightly fragrant on trees that reach heights of 50 feet or more. The large evergreen leaves give this plant an attractive tropical appearance and the bright red seeds provide excellent fall color (the seed pods are large enough to look like large red flowers from a distance). Unlike many other Magnolia species which produce all of their flowers in a single spring crop, Giant Evergreen Magnolia trees produce additional large flowers throughout the summer following the main crop in late spring. 
Many gardeners have reported that this Magnolia will thrive in zone 6, but the leaves will typically be deciduous and the trees will stay closer to 30 feet tall. Plants will perform their best when grown in rich soil but can tolerate other soils as long as their roots aren't extremely over or under-watered. Magnolias are sensitive to over-fertilizing so it is best to use a slow release pellet like Osmocote or tree fertilizer stakes.

Magnolia grandiflora is known as the Southern Magnolia, a dominating landscape element throughout the southern states, often thought of as the symbol of American South. Heat resistant and tolerant of damp soil but requires protection from cold winter winds, ice, and snow. The slow growing tree does require maintenance, a lot of water, and the roots can lift walks, but the tree provides dense, year round shade. Leaves are leathery in texture, dark glossy green above, thick, red-brown felt underneath. Large, creamy white flowers with lemon scent can grow to 14" across and are borne from May-June. You will find that the leaves regenerate and fall May-September. Fruit is borne September through November. Grows to 60' height.
