Polemonium boreale is found in all regions of the High Arctic. It is therefore very cold hardy and prefers a cool, moist soil. It resents strong sunlight (especially in periods of drought). It forms compact mounds which slowly spreads by underground stems. The pinnately compound leaves will be familiar to anyone who has grown Jacobs Ladders before. They consist of 13-23 green leaflets covered in woolly hairs which make it sensitive to high humidity. The foliage dies back in the autumn and re-appears in the spring.

Polemonium boreale Heavenly Habit bears very attractive clusters of violet-blue flowers, each with a distinct pale golden yellow eye. The flowers are held above the leaves on short stems and contrast well with the bushy, deep green foliage. This dwarf Jacobs Ladder is ideal for the front of borders, containers and the edge of paths. Regular dead-heading encourages flowers all summer.
