Lupinus arcticus subsp. subalpinus
Lupinus arcticus subsp. subalpinus
The Subalpine Lupine thrives in cool, partly shaded spots with consistently moist, well-draining soil — ideal for rock gardens or naturalized mountain-style landscapes in the Pacific Northwest. Plant it where it receives morning sun and afternoon shade, and avoid waterlogged conditions. As a nitrogen-fixing legume, it improves soil health and requires minimal fertilization.
