Sand dunes along the Lake Michigan shore. There is a strange gap in the distribution between western Michigan and the dunes of Indiana and Illinois. The range is otherwise to the west, as far as the Pacific but for an isolated station on Manitoulin Island. The only documented host in Michigan appears to be Artemisia campestris on sand dunes, although other hosts have been reported elsewhere.
The flowers are similar to those of O. uniflora, with which this is sometimes confused. O. uniflora has an erect, buried stem, which should not be mistaken for the above ground stem of O. fasciculata when keying specimens.
