The Outer Banks spans USDA hardiness zones 8b-9a — a zone band wide enough that plant choice, not possibility, is the interesting question.
A wind-swept barrier-island chain of pure sand and salt spray, where hardy figs, greens, and dune-edge kitchen gardens hold on against the Atlantic. Growers here do well with sweet potato, blueberry, muscadine grape, and dogwood — with the usual caveat that any single yard's soil, sun, and drainage cast the deciding vote.
