Showy Ticktrefoil, PA Ecotype

Showy Ticktrefoil (Desmodium canadense) is an erect-growing, clump-forming perennial wildflower that can grow to a height of 4.9 ft. Desmodium canadense has trifoliate leaves in alternate positions on the stem and produces purple flowers in late summer. The fruit of Showy Ticktrefoil are legumes (pods), 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 in areas between 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. We do not recommend including Desmodium canadense in residential meadow mixes because the seed sticks to clothing. 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 pea (Fabaceae) family. The Latin name “Desmodium” is derived from the Greek word meaning “band” or “chain”, referring to the joined pods.
