The Arctic Lupine is a hardy perennial suited to cold climates, preferring partly shaded to full-sun positions with moist, loamy soil. It is highly cold-tolerant and well-adapted to subarctic and boreal environments, making it an excellent choice for northern gardens. Being a legume, it fixes atmospheric nitrogen and enriches the soil around it with little need for added fertilizer.
