is a well-known calciphile (favoring alkaline or lime-rich habitats) and as with most insectivorous plants, prefers wet substrates. It is found in moist alkaline rock crevices and outcrops; rocky or gravelly shores, sandy, interdunal shoreline flats; marshy soils near bogs, wet alvars, and the marly, calcareous soils of coastal and northern fens. It also occurs in Lake Superior coastal areas where it inhabits volcanic bedrock lakeshore areas, favoring basalts and conglomerate bedrock types. Most Michigan locations are along Great Lakes shores, particularly on rocky, wet beaches and nearshore wetlands and interdunal areas.
