Which of the following plants is native to the southeastern United States?

Morella cerifera, commonly known as wax myrtle, is indeed native to the southeastern United States. It is often found in regions with moist, sandy soils and is commonly associated with coastal areas and wetlands. This plant is valued not only for its aromatic leaves but also for its utility in landscaping due to its adaptability and resilience.

Nandina domestica, or heavenly bamboo, and Loropetalum chinense, or Chinese fringe flower, are both originally from Asia, while Nerium oleander is native to the Mediterranean region. Therefore, these plants do not qualify as native to the southeastern United States, which reinforces why Morella cerifera stands out as the correct choice in this context.
