Historical Notes: This showy North American orchid is native to acid-bogs and moist prairies in Wisconsin, but is easy to grow in many regions of the United States with proper care. The genus Calopogon derives from the Greek terms kalos and pogon, meaning "beautiful beard," in reference to the cluster of hairs that adorn the lower petal. This species was first discovered in North America in the 1770s. Lady Skipwith mentions Calopogon pulchellus in her late eighteenth century writings.1 Peter Henderson's reference to Calopogon, in his Henderson's Handbook of Plants and General Horticulture (1890), notes: "Like most of our native Orchids, it improves by cultivation."2
