This understated little plant, polygala alba, blends in with the grasses and can be difficult to spot. I found a few clusters this morning in some open, sparse areas alongside a road. Don’t confuse it with its relative, seneca snakeroot (polygala senega). For a year or so, I had seneca snakeroot identified as white milkwort, until I finally decided both couldn’t be milkwort and needed to just figure it out. Thanks to the book Plants of the Black Hills and Bear Lodge Mountains, the mystery was solved.
Very pretty plant. I’ve not seen that before.
