Arctic lupine’s blue and purple buds are a stunning sight against the otherwise grassy, snowy, or rocky alpine slopes of the tundra. Preferring wide-open areas with plenty of room to spread, these bushy plants can actually enrich soils with low nitrogen levels, making them a great asset for areas that lack minerals.5 Their wooly stems help trap heat and protect them from the wind.
