    Jacob's Ladder gets its name from the arrangement of its leaves – pairs of opposite leaflets resembling a ladder. In early summer, erect stems rise up from the bright green foliage carrying clusters of bell-shaped, lavender-blue flowers. A cottage-garden favourite, Jacob's Ladder is happiest in partial shade, and looks equally at home in a wildlife garden setting or in grass. Although it is short-lived, it self seeds freely.

  • Garden care: Cut the plant back after flowering to encourage a second flush of flowers. In autumn cut the faded flowerheads down to the ground and compost the dead stems.

Comments about Crocus Polemonium caeruleum:

Lovely plant with spires of sweet scented cheerful bold blue flowers with contrasting bright yellow stamen. The bees and hoverflies (etc) love it too which is great.

Seemed to need quite a bit of watering but this is the only issue i have
