Shortia galacifolia Torr. & A. Gray
Although native to North America, you aren’t likely to find these outside a garden, since they are extremely rare. After identification in 1788, nearly a century elapsed before it was spotted again.
Identification: Technically, this evergreen plant qualifies as a tiny shrub, though, at a height of about 6" (15 cm), most would classify it as a herbaceous plant. Leaves are round, ¾-2½" (1.9-6.3 cm), with long stems and gently scalloped edges, very glossy. Flowers about ¼" (6.3 mm) in diameter appear atop short stems. They are white or pinkish, with delicate frilled edges like pinks and five petals.
