“Desmodium canadense is aptly named Showy Tick Trefoil for its numerous pink flowers that bloom along the plant’s upper stems for about three weeks in mid-summer. The effect is more attractive in colonies than isolated plants and tight plantings can help counter a tendency to sprawl. Like other tick trefoils (legume), Desmodium canadense adds soil nitrogen and has tiny hairs along its stems, leaves and seedpods, facilitating seed distribution by passing mammals and humans. The nectar, pollen, seeds and foliage of this species appeal to a number of insects, birds and mammals.”
