Desmodium glutinosum

Pointed-leaved Tick-trefoil

 

A distinctive native perennial of open woodlands, woodland edges, savannas and dry to mesic forests, Pointed-leaved Tick-trefoil is a member of the pea family. Its upright stems and characteristic three-part leaves make it easy to recognize once established.

The foliage is often somewhat sticky or glandular, particularly along the stems and leaves, giving the species its name. Small pink to purplish pea-like flowers appear in slender clusters through mid to late summer, attracting a variety of native pollinators.

After flowering, the plant produces segmented seed pods that readily attach to passing animals, helping spread the species through woodland habitats.

Growing Conditions

Light: Part shade to full sun
Soil: Well-drained, average to dry soils; adaptable to a range of woodland soils
Moisture: Dry to medium
Height: 60–120 cm

Ecology

Desmodium glutinosum is particularly valuable in woodland restoration and naturalized plantings, where its legume family roots contribute to soil nitrogen cycling. It works well alongside woodland grasses, sedges and other native herbaceous species.

Like other tick-trefoils, its jointed seed pods are adapted for animal dispersal, allowing populations to gradually move through connected natural areas.

Larval host: Several native moth species, including members of the Schinia genus, use Desmodium species as host plants.

Native range: Eastern and central North America, including southern Ontario.
