(Muhlenburg ex Willdenow) Rafinesque
Middlesex, Norfolk and Oxford Counties have yielded sightings over the years. In 1985, only Oxford County yielded a blooming plant. Southern Ontario inland from Lake Erie is the northernmost range for this orchid of the eastern United States.
Dry to damp hardwoods to mixed forests, and along the mossy edges of fens. Plants usually occur in fairly large colonies, but appear sporadically, often not flowering for several years.
|Flowering Season||Late May to early June.|
Height: to 30 cm. Stem smooth, slender, purplish, hollow.
To distinguish the non-flowering plant from one of the rare I. Medeoloides, one should compare the stems: The stem of the later is shorter and thicker, whitish green rather than purplish. Both stems are hollow, which distinguishes them from the more slender, fuzzy solid stems of Medeola virginiana (Indian Cucumber) with which it often grows. Also, the leaves of I. Verticulata tend to be a darker green and more blunt than I. medeoloides.
