The leaves are ovate, 2–6 cm and coarsely dentate. The flowers and fruits are clustered near the top of the fruiting raceme; each raceme bears 15 or less white or pink flowers in July. The seed is a bur with one seed. C. alpina prefers a moist, upland habitat.[2] C. alpina can reproduce vegetaively and via stolons.[1]
