Safety Overview
1.Desmodium Canadense — Overview
Desmodium canadense, commonly known as Showy Ticktrefoil, is a resilient perennial legume native to North America, belonging to the Fabaceae family. This robust herbaceous plant typically reaches heights of 3 to 4 feet, though it can extend up to 6 feet under optimal conditions, exhibiting an erect growth habit with stems covered in fine white hairs. Its distinctive foliage consists of trifoliate, compound leaves arranged alternately, featuring lanceolate leaflets measuring 2 to 3.5 inches in length with rounded tips and fine, hooked hairs on their undersides.
During mid-summer, from July to August, the plant bursts into vibrant bloom with pea-like flowers, approximately half an inch in size, displaying shades of pink to purple, often accented with a darker pink and yellow patch at their center. These unscented blossoms are densely packed along elongated racemes on the upper half of the plant, sometimes giving it a graceful, nodding appearance. Following pollination, the flowers develop into flattened, segmented seed pods known as loments, typically 2.5 inches long with 3 to 5 segments, covered in tiny hooked hairs that readily adhere to clothing and animal fur, aiding in seed dispersal.
Showy Ticktrefoil is widely distributed across the central United States, extending northward into Canada, as far west as the Dakotas, and eastward to the Atlantic coast from Virginia to Maine, thriving in diverse habitats. It is commonly found in tall grass prairies, along riverbanks, lake edges, and wet meadows, but also adapts well to open woods, rocky and sandy prairies, roadsides, and disturbed areas, preferring full sun and moist, well-drained loamy soils.
