Magnolia macrophylla ((bigleaf magnolia)

Bigleaf magnolia is a deciduous magnolia with bragging rights for having the largest simple leaf and single flower of any native plant in North America. It is a rare, native, deciduous tree with a single trunk and develops a spreading, broad, rounded crown with maturity. Grows to 65' tall. Leaves can measure up to 3' long and 1' wide. The fragrant creamy-white flower is typically about 16" wide. Bigleaf magnolia grows best in moist, organically rich, well-drained loams with acidic or neutral soil, and in full sun to partial shade. It may take 12 or more years before the first blooms appear. Give it space so it can reach its full potential, preferably in a place where it is protected from urban pollutants and strong winds. Generally intolerant of dry and wet soils. No serious insect or disease problems. Usually low maintenance except when the leaves fall.

Bigleaf magnolia is native to the southeastern U.S. and eastern Mexico. Like all magnolias, it is beetle-pollinated. Birds eat the seeds.
