Other info. - Although this species can be found throughout much of Missouri, it is most common in the Ozark region where it is a characteristic glade and dry upland species. The plant is easy to identify because of its habitat, its light green-blue stems, and its long rhizomes. The plump, light-colored fruits are another good character to use for identification. The plant is sometimes found in more mesic areas and will grow taller and less erect than in the dry locations.
