Polemonium caeruleum
Jacob’s Ladder |
USDA Zone: 2-9 |
Plant number: 1.427.050
An easy perennial, especially for beginning gardeners. Plants form a lush mound of deep green, ferny foliage, bearing upright stems with star-shaped blue or white flowers, held in small heads beginning in late spring. The flowers are similar to Phlox, and good as a cut flower. Tends to self seed prolifically, but cutting off the spent flower heads will help to prevent this. Evergreen in mild winter regions. Easily divided in early spring or fall.
