Large-leaved Lupine (Lupinus polyphyllus)

Origin:
Western United States and Canada. Introduced to Europe to improve the soil on roadsides and in coniferous forests and as an ornamental plant (19th/20th century).

Location:
Bigleaf Lupine can be found from low to middle elevations in open and moist habitats. It prefers well-drained soils and often grows along roadsides, riverbanks, and in disturbed areas.

Influence:
The species has a strong impact on alpine mountain hay meadow communities because it changes the structure of usually low-growing vegetation. In its introduced range Bigleaf Lupine suppresses local plants and reduces the abundance of butterfly species.

Recognition:
Bigleaf Lupine’s steam is upright, unbranched and can grow up to 1.5m. Its flowers are purple or purple-blue and have a pea-like shape. Bigleaf Lupine has long-stalked basal leaves which are composed of 10-17 leaflets and can grow up to 25 cm in diameter.
