I love the beautiful colors they turn in the spring. They look so lovely and beguiling. And they are, as long as you stroke them from the stem upward. But try to stroke downwards, and your hands and fingers will get barbed splinter-like spikes. If dogs tangle with foxtails, they usually end up at the vet’s in a great deal of pain. So admire them from afar, but don’t tangle with them.
