Southern magnolia
Magnolia grandiflora
A large evergreen tree of the southeastern US coastal plain with thick glossy oblong leaves (rusty undersides), enormous (8-12 inch) creamy-white cup-shaped fragrant flowers in late spring through summer, and conspicuous red-seeded cone-like fruit in fall. Beetle-pollinated - the magnolia genus evolved before bees existed and retains the ancient beetle-pollination relationship documented per NC State. Year-round leaf drop and dense canopy mean almost nothing grows beneath; site with that constraint accepted.
Native: 12 US states
