POTD: Prairie Smoke #4

Prairie Smoke #4
Bozeman, Montana

Based on the first wildflower book we bought when we moved to Montana almost 40 years ago, we learned to call this flower species, genum triflorum, by the common name hooded avens. We also learned that they are also referred to as prairie smoke. It turns out that prairie smoke is by far the most commonly used common name for the species and that no one else, even various internet sources calls them hooded avens. They’re called purple avens at times but never hooded avens. I need to dig out that old flower book and see if we were just imagining the name.
