Also called snakehead and balmony, this herbaceous perennial is a member of the plantain family, Plantaginaceae, that also includes foxglove, snapdragon, and angelonia. It is native to North America from Newfoundland to north Georgia, and west to Minnesota where they grow in wet areas such as riparian forests, flood plains, and swamps. Growing 2’3′ tall from a rhizomatous rootstock, the plants form stiff clumps of erect stems bearing sessile, lanceolate , toothed leaves 6-8″ long. Clusters of 1″ long flowers appear in terminal compact spikes in summer for three to four weeks. They are white sometimes tinged with rose, two lipped, and supposedly resemble turtle’s heads. Since turtlehead grows best in moist soils in part shade they are a good choice for shade, bog, and woodland gardens as well as on the edges of ponds and streams. The genus name, Chelone, is the Greek word meaning tortoise. The specific name, glabra, comes from the Latin word glaber meaning hairless.
