Schoenolirion croceum is very localized on limestone outcrops in central Tennessee and northern Alabama, sandstone outcrops of the Alabama plateau region, granite outcrops of the Georgia and Carolina Piedmont, Selma chalk outcrops in western Alabama, and wet pinelands and boggy areas in more southern and western parts of its range. All of these habitats are very wet in spring and often very dry in summer.
