Vicia villosa | Botanical Characteristics
Common Names: Hairy Vetch, Winter Vetch
Family: Fabaceae
Appearance: A climbing or trailing annual legume with slender, hairy stems, pinnate leaves ending in branched tendrils, and clusters of purple to violet pea-like flowers followed by elongated seed pods.
Type: Annual
Evergreen / Deciduous: N/A
Layer: Groundcover
Root System: Deep taproot with extensive fibrous lateral roots and nitrogen-fixing nodules
Height: 0.3–1.5 m (when supported)
Width: 1–3 m (spreading)
Lifespan: Annual
Growth Rate: Fast
Fertility: Self-fertile
Flowers: Hermaphroditic
Pollinator: Bees and other insects
Toxicity: Seeds may be toxic to humans and livestock if consumed in large quantities due to cyanogenic compounds and other anti-nutritional factors; foliage is generally safe when grazed before seed set.
