Buy Polemonium caeruleum Jacobs ladder: Bell-shaped, lavender-blue flowers in early summer.


  • Position: full sun or partial shade
  • Soil: fertile, moist, well-drained soil
  • Rate of growth: average
  • Flowering period: June
  • Hardiness: fully hardy

    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.

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

How far should I cut this back if I want to try and get a second flush of flowers?

Amanda

Hello, If you cut the top back to lush basal growth after all the flowers have faded, then you may get a second flush in late summer.

What can I plant in my planting bed? I have lost a plant in the middle of a border and am left with an unsightly hole which I would like to fill with some colour again. It is a narrow border so I don't want anything too large - probably no bigger than 50x50 cm. It is a mixed shrub/perennial border of pink, blue and white, which gets lots of sun and tends to be fairly dry - the soil is clay. The surrounding plants are perennial cornflower, hardy geraniums and osteospermum. Can you recommend something which will quickly fill the gap?
