Comprehensive DescriptionRead full entry
CommentsThe flowers of this small orchid have an unusual spidery appearance. Lacking bright distinctive colors, they have a tendency to blend into the background. Because no other orchid in Illinois closely resembles Purple Twayblade, it is easy to identify. Its nearest relative in the state, Liparis loeselii (Lesser Twayblade), has less showy flowers that are smaller in size, yellow-green, and self-fertile. Instead of Purple Twayblade, other common names of Liparis liliifolia are Large Twayblade and Lily-Leaved Twayblade.
