This species was not collected until 1933 (Menominee Co.) and is probably not native in Michigan, although its normal habitat (west and northwest of the Great Lakes) is sandy or gravelly grasslands, shores, clearings, and other ± disturbed ground, so that the native range is not always clear.
The limb of the pink to bluish corolla is only 3–6 mm broad, and the compact inflorescence is well overtopped by the upper leaves (or bracts), so this is not a conspicuous plant even when in bloom.
