Blue Pearl Jacob’s Ladder


Blue Pearl Jacob’s Ladder

Polemonium caeruleum
(90 days) A staple of the shade garden in cooler climes. Where so few plants flower, Blue Pearl shines. Sky blue 1–1½" cup-shaped blooms with distinctive gold stamens flower from late spring to early summer except in extreme heat. The long-lived compact 1' plants perform best in partially shaded borders, at the edge of woodlands or at the base of small shrubs or roses. Space 1' apart. Called Jacob’s Ladder for the arrangement of parallel leaflets along the stem. Makes a beautiful cutflower. Perennial, Zones 3-8. ~850 seeds/g.
