DescriptionGrowing alone or in small colonies, grass-pink is the showiest of the bog orchids. The flower stalk, which grows 18" tall (or more) from a small white bulb, bears a loose raceme of bright pink to magenta flowers. Because the lip is at the top of the flower, grass-pink appears to be an "upside down" orchid.
