Northern Jacob's Ladder, Arctic Jacob's Ladder
Extremely cold-hardy, Polemonium boreale (Northern Jacob’s Ladder) is a compact perennial with creeping underground stems forming a low, bushy mound of alternate, basal green leaves with very short petioles. The pinnately compound leaves, each adorned with 13-23 leaflets, are covered with long woolly hairs. In late spring to early summer, it is smothered with a profusion of unpleasantly scented, small sky blue flowers, adorned with a yellow eye and white stamens. They are highly adapted to insect pollination. Excellent for rock gardens or in the front of borders.
