This perennial dies back to below ground level each year in autumn, then fresh new growth appears again in spring.

  • Position: full sun
  • Soil: fertile, well-drained soil
  • Rate of growth: average
  • Flowering period: June to July
  • Hardiness: fully hardy

    Powder blue flowers, each with a white eye, are evenly spaced along the stout flower spikes, creating towering columns of colour. Their elegant, upright shape is useful for creating vertical interest in mixed planting schemes where they associate particularly well with echinaceas, iris, paeonies and eryngiums.

  • Garden care: For best results, choose an open spot away from taller plants. Stake with bamboo canes as they start to shoot upwards in mid-spring and protect young foliage against slug and snail damage. During the growing season, apply a balanced liquid fertiliser every 2-3 weeks and wearing gloves cut back the faded flower stems to a flowering side-shoot to encourage repeat flowering. At the end of autumn cut back and compost the faded flower stems.
  • Harmful if eaten
