Magnolias (​Magnolia​ spp.), hardy in U.S. Department of Agriculture plant hardiness zones 4 through 9, depending on the species, are large, elegant trees that produce showy flowers during the spring. They are excellent choices for ornamental flowering trees in Illinois gardens. Illinois has hardiness zones that range between 4 and 6, so choose a magnolia species that is cold-hardy and prospers in the growing zone where you call home.
