Habitat: Sandy ground everywhere except in the Cape May peninsula. Stone says common in both dry and moist situations; an abundant plant in the Pine Barrens.
"The Pines seem to be the chosen land of the Ericaceae, which abound there both in species and individuals. As we visit them in early spring in search of the finest Arbutus that I know of, so by the end of June we may be sure of finding the greatest display of Laurel that can be found anywhere in the Middle States even on the mountains themselves, which are supposed to be its proper home. It is snow white in shady spots and reaches a height of six to eight feet, while in open ground, even out on the plains, it grows in low rounded bushes with the flowers of the deepest pink. " (Stone 617)
