Arctic Jacob’s Ladder (Polemonium boreale ‘Heavenly Habit’)
USDA Zone: 3-9.
This selection of Jacob’s Ladder is a terrific choice for edging in the border, or using in rock gardens or containers. It forms a low, bushy mound of ferny green leaves, bearing loads of violet-blue, starry flowers, each with a white eye. Blooms appear over a long season. Clip back by half in midsummer to rejuvenate, if necessary. Clumps may be easily divided in early fall or spring. Prefers an evenly moist soil and partial shade, particularly in warm summer regions.
