Fun, weird, helpful, or little known fact
Our local Mules ears are unusual in that their leaves have a rough-hairy texture, while most W. amplexicaulis plants are smooth and hair-free. William Weber, the foremost authority on Colorado wildflowers, says ours is “a stable hybrid population stemming from a time when the Pleistocene climate compressed the range, bringing this species into close contact with W. arizonica.”
