Showy Ticktrefoil, PA Ecotype

Desmodium canadense (Showy Ticktrefoil) is an erect-growing, clump-forming perennial wildflower that grows to 4.9 ft. Desmodium canadense has trifoliate leaves in alternate positions on the stem and produces purple flowers in late summer. The fruits of Showy Ticktrefoil are legumes, or pods, that are long and flat with three to five joints and hairs that allow them to attach to fur or clothing. Desmodium canadense is a nitrogen-fixing native wildflower that naturally occurs from eastern North Dakota, central Oklahoma, Virginia, and Maine. Showy Ticktrefoil is found in thickets, riverbanks, open woods, and meadows. Desmodium canadense tolerates full sun to partial shade. We use Showy Ticktrefoil in wildlife-friendly upland, partially shaded, and riparian meadow mixes. Because the seed will adhere to clothing and fur, we do not recommend including Desmodium canadense in residential meadow mixes. Showy Ticktrefoil is pollinated by a variety of native bees, including those in the genera Bombus, Heriades, Megachile, and Melissodes. Deer and various game birds use Desmodium canadense for food and cover. Showy Ticktrefoil is a member of the Fabaceae, or pea, family. The Latin name Desmodium is derived from the Greek word meaning a band or chain, referring to the joined pods.
