Magnolia macrophylla Michx.
Magnoliaceae (Magnolia Family)
USDA Symbol: MAMA2
The tree with the largest flowers and the largest leaves of all native North American species (except for tropical palms) and a broad, rounded crown of stout, spreading branches. Big-leaf magnolia is a round-headed giant reaching 30-40 ft. in height. Flowers are creamy-white, 8-14 in. across, solitary and fragrant, followed by egg-shaped, rose-colored fruits. Deciduous leaves are extremely large, up to 1 ft. wide and 3 ft. long.
Planted as an ornamental north to Massachusetts. However, in windy places the giant leaves become torn and unsightly. The "queenliest of all the deciduous magnolias" was named by the French naturalist and explorer Andre Michaux (1746-1802), who discovered this rare local tree near Charlotte, North Carolina in 1789.
