Lupinus burkei, commonly known as Largeleaf Lupine, Burke’s Lupine, or Subalpine Lupine, is a perennial herb that thrives in the mountainous regions of the western United States and Southwestern Canada. It is particularly adapted to subalpine meadows and open, montane forests, where it contributes to the ecosystem by fixing nitrogen in the soil. Lupinus burkei grows at a moderate rate to a typical height of 1-2 feet (0.3-0.6 meters) and a width of 1-1.5 feet (0.3-0.5 meters). This species is characterized by its palmate leaves and spikes of blue or purple flowers, which are highly showy and attract pollinators when they bloom in the summer. The plant’s foliage can add texture to garden settings.

Largeleaf Lupine is valued for its ornamental flowers and ability to adapt to mountainous garden conditions. It is often used in native plant gardens, meadowscapes, and as a border plant. While it prefers full sun or part shade, it is versatile and can tolerate medium draining loam or clay soils. Regular watering is necessary, especially in drier climates. Gardeners should be aware that Lupinus species can be toxic to livestock and pets if ingested. Additionally, they may suffer from aphid infestations or root rot in poorly drained soils.CC BY-SA 4.0
