The stems have barbed hairs pointing downward and these hairs make the plant rough to the touch. Ragged Robins bloom from May to August, occasionally later, and butterflies and long-tongued bees feed on the flowers nectar. The fruits consist of small (6-10 mm) capsules opening on top by five teeth and containing many small seeds, they are found on the plants from August onwards.
