Iliamna remota is known from Langham Island opposite Altorf in the Kankakee River (about nine miles northwest of Kankakee, Illinois), where it persists as the only certain wild locality; it now may occasionally escape from cultivation or deliberate introduction, as apparently was the case of a naturalized population found in the 1940s in swale about two miles east of New Paris, Indiana. It was apparently distributed along railroads by enthusiastic wildflower groups in the last century. Iliamna remota is listed as endangered by the state of Illinois.
