Lupinus latifolius (Broadleaf Lupine)

Broadleaf Lupine, Broad-Leaved Lupine, Bigleaf Lupine, Riverbank Lupine, Lupinus rivularis


Native to California and the Pacific Northwest, Lupinus latifolius (Broadleaf Lupine) is a bushy, densely branched perennial forming an extensive clump of large, palmately compound leaves with 5-10 leaflets up to 4 in. long (10 cm). In late spring to fall, it boasts showy racemes, 4-12 in. long (10-30 cm), of purple to blue to white pea-shaped flowers. They are borne on stout, erect stems, well above the attractive foliage and attract bees, butterflies and many pollinators. The blossoms are followed by densely hairy pods which contain 6 to 10 dark brown seeds. Broadleaf Lupine spreads by seed and root sprouts to form spectacular colonies. Broadleaf Lupine is a nitrogen-fixing legume. It is valuable for rehabilitation of disturbed sites because it grows well on droughty and low-fertility sites, colonizes disturbed areas, has a deep root system for stabilizing soil, and forms associations with nitrogen-fixing bacteria. It is commonly used for erosion control.

  • Grows up to 1-4 ft. tall (30-120 cm).
  • Thrives in full sun to part shade in moist, shallow, coarse-textured, rocky and fast draining soils. Broadleaf Lupine can persist in low-fertility soils because of its ability to fix nitrogen.
  • An excellent choice for informal gardens, prairies and meadows.
  • No serious pest or disease issues.
  • Propagate by seed. Fresh seeds need no treatment.
  • All parts, particularly the seeds, may cause severe discomfort if ingested. Toxic only if eaten in large quantities. Wear gloves and wash hands after handling.
  • Toxic to dogs, toxic to cats, toxic to horses, toxic to humans.
  • Native to western North America from British Columbia to Baja California to New Mexico.
