If you’ve ever seen this wildflower, you know the name was created to simply describe the flower. The little dangling two-legged blooms clearly resemble pairs of pants hung out to dry. And of course, a common name like this makes its own history. To many serious Victorians, the name, “Dutchman’s Breeches” was considered an unrefined abomination, even though the flowers of this wildflower do resemble pantaloons.
