Harebell is occasional in those few Black Oak savanna remnants that still have a little sunlight getting in, and abundant on thinly wooded foredunes near Lake Michigan. Its thin stems allow it to dance on the breeze - rather delightful until you attempt to get a photo. Cauline leaves are linear - the species name refers to basal leaves that are somewhat round in outline, though in my view they tend to be reniform.

The French fur trappers called this little subshrub "Petit The Des Bois," meaning "Little Tea of the Woods."
