The vegetation of the Outer Banks has biodiversity, although it is considered the northern limit for many southern plants such as wild scrub palms. In the northern part of the Outer Banks, from Virginia Beach southward past the North Carolina border to Cape Hatteras, the main types of vegetation are sea grasses, beach grasses and other beach plants including "Opuntia humifusa" on the Atlantic side and wax myrtles, bays, and grasses on the Sound side with areas of pine and Spanish moss-covered live oaks. "Yucca aloifolia" and "Yucca gloriosa" can be found growing wild here in the northern parts of its range on the beach. Sabal Minor palms were once indigenous to the entire Outer Banks, and they are still successfully planted and grown. Its current most northerly known native stand is on Monkey Island in Currituck County.
