Quick Summary

The term "twayblade" refers to orchids from the genera Liparis and Neottia, within the family Orchidaceae. The name originates from the two characteristic leaves found at the base of the flowering stalk.1

The large twayblade (Liparis lilifolia) is an orchid native to eastern North America. It is distinguished by its lustrous, elliptical to nearly ovate leaves, an angled scape, and a terminal raceme bearing 5 to 40 flowers that are typically purple and green, or sometimes entirely green. This species is part of the Liparis genus, also known as false twayblades, which includes about 320 species of epiphytic and terrestrial orchids found globally.21
