In Ky. this northeastern species is known for certain only at high elevation on Black Mt. (HARL). There are also sightings reported from MENI, POWE and WOLF by several people (Campbell et al. 1989; KSNPC), but these may all have been based on unusual forms of peramoena with less fringing. It is reported to flower relatively early, mostly in Jun to Jul; see also FNA 26.
