Buy Cynara cardunculus cardoon: Attractive thistle-like flower-heads

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 September
  • Hardiness: fully hardy

    Huge, purple, thistle-like flowers from June to September held above enormous clumps of deeply-cut, silvery-green leaves. This magnificent, architectural plant is perfect towards the back of a mixed or herbaceous border. For the best results it needs full sun, lots of space and shelter from strong winds.

  • Garden care: Avoid the temptation to remove the faded flower-heads in autumn as they provide interest in the winter garden. Where temperatures fall below -15°C (5°F) protect the crown of the plant with a dry winter, straw mulch.

Never thrived

plant never really thrived. Was weedy and floppy in yr 1, with no sign of a flower, it came back well in yr 2 but leaves were floppy and scoured - and prey to snails. Has now collapsed with no hope of resurrection.

I need to add to the Thistle plants already in my garden to increase the " show " I have bought from you before with excellent results. How are the plants supplied and when do I cut back the existing for re growth. I have read regarding leaving the tops on in winter. Thank you.

Keen gardner with no idea

Hello there We sell these in 9cm or 2lt pots. http://www.crocus.co.uk/search/_/search.Cynara-cardunculus/sort.0/ We say to leave the flowerheads for interest in the winter garden, but if they go brown and soggy I would cut them back. If we have a cold winter and temperature falls below -15°C (5°F) I would protect the crown of the plant with a dry, straw mulch.

Bare root beauties-Thistles! Hi We bought some ornamental thistle plants from you earlier this year which have grown really well and the thistles were superb. The thistles are starting to die off now can you tell me what to do with plants and the thistles now that winter is coming on. Thank You Gill

Hello Gill, I think you purchased the Cynaras, so you should avoid the temptation to remove the faded flower-heads in autumn as they provide interest in the winter garden, and if temperatures fall below -15??C (5??F) protect the crown of the plant with a dry, straw mulch now. I hope this helps. Helen Plant Doctor
