Arctic lupine
Lupinus arcticus
Arctic lupine is a striking perennial native to subarctic regions that produces tall spikes of vivid blue-purple flowers in late spring and summer. It thrives in cool climates with well-drained, slightly acidic to neutral soil and requires little fertilization thanks to its nitrogen-fixing root nodules. Plant it in a sunny to lightly shaded spot and it will reward you with bold color and excellent wildlife value.
