About Polemonium boreale Adams
Polemonium boreale, commonly called northern Jacob's-ladder or boreal Jacobs-ladder, is a plant species native to most of the high arctic. In Greenland, it is only found in a small area along the east coast, and it is not a very common species overall. The entire plant is covered with long woolly hairs, is glandular, and grows to a height between 5 and 10 cm. Its basal leaves are roughly alternate in arrangement, pinnate, and bear numerous leaflets. The flowers grow in a roughly capitate inflorescence; each individual flower is bell-shaped, blue, 15 mm long, and 2.5 times the length of the calyx. Polemonium boreale has a very unpleasant smell, and it typically grows on gravelly slopes and in crevices.
