Hairy Vetch

Brief Description

A climbing or sprawling leguminous herb with clusters of purple flowers and pinnately compound leaves.

Characteristics

Vine-like stems with tendrils for climbing; pinnate leaves with 10-20 leaflets; dense one-sided clusters (racemes) of violet to purple tubular flowers; stems and leaves are covered in fine, spreading hairs.

Habitat

Found in fields, roadsides, disturbed areas, meadows, and as a cover crop in agricultural lands.

When to Find It

Spring to early summer (typically April to July).

Conservation Status

N/A (often considered weedy or invasive in some regions).

Ecological Role

As a legume, it fixes nitrogen in the soil; it provides nectar for bees and butterflies and serves as forage for various livestock.

Easily Confused With

Bird Vetch (Vicia cracca), which is less hairy and has shorter flowers; Winter Vetch (Vicia sativa), which usually has flowers in pairs rather than long clusters.

Observation Tips

Look for it trailing over other vegetation in sunny, open areas. It is easily identified by its hairy stems and the lopsided arrangement of purple flowers.

Interesting Facts

Hairy vetch is often used by farmers as a winter cover crop to prevent erosion and improve soil fertility through nitrogen fixation.
