The Bigleaf Magnolia (Magnolia macrophylla) is a deciduous magnolia native to the southeastern United States and eastern Mexico. Known for having the largest simple leaves and single flowers of any North American native plant, it can reach heights of 50 to 65 feet. The leaves can be 10 to 32 inches long and up to 18 inches wide, while the flowers can measure up to 21.5 inches across, making it the largest temperate flower in the world. These large white flowers with purple blotches at the base are beetle-pollinated, and the tree produces cone-like clusters of achenes with seeds covered in an orange aril. Conservation Status: Bigleaf Magnolia is listed as threatened in North Carolina and endangered in Arkansas and Ohio, while the Ashe Magnolia is considered endangered in Florida. The Mexican Bigleaf Magnolia is also endangered due to habitat destruction. Illegal and legal collection practices can negatively impact its populations, particularly where numbers are already low. Cultivation Requirements: Bigleaf Magnolia requires specific conditions for successful cultivation, including loose, rich, moist, well-drained soils with a low pH, in full sun or part shade. It is sensitive to wind due to its large leaves and benefits from a location that mimics its natural habitat. Although it can grow further north than its natural range, it requires consistent watering during dry periods.
