Infrequent in tussocks of sphagnum moss in the open and in tamarack bogs; very rarely in moist sand with such species as Polygala cruciata, Gaultheria procumbens, and Aletris farinosa. In 1915 it was so abundant on the moist, sandy shore of Walker Lake, Porter County, that it covered acres, and at a distance, the ground looked red. This and the next species [Drosera intermedia] are restricted to the lake area.
