Fun, weird, helpful, or little known fact
First, importantly, not all thistles are “bad”—i.e., non-native invasives—and indeed with a little time and attention paid can take on a certain charm (in addition to being pollinator favorites). This thistle is common (but not TOO common) on the Pass, from the montane to the alpine in meadows and forest openings. It has white, pink, or purple flowers protruding up from its cobwebby head. Its stem is often dark red (below) and its leaves are spiny. It has learned well how to protect itself!
