Key benefits

  • Blue, pink, red, lavender, white and maroon from one sowing
  • Cut flowers that last well in a vase and dry nicely
  • Bees and butterflies visit all summer
  • Grows around 40 to 50 cm tall, even on poor ground
  • Packet of about 150 seeds with growing instructions

'Polka Dot Mix' takes the classic cornflower and adds a whole palette: blue, pink, red, lavender, white and deep maroon from a single sowing. The frilly, button-like flowers of Centaurea cyanus sit on wiry, silver-green stems from early summer, and they keep coming if you cut them. They last well in a vase, dry nicely and look at home in a cottage border, a wildlife patch or a large patio pot. Bees and butterflies visit all summer, and the goldfinches often take the seed heads in autumn if you leave a few.

Frequently Asked Questions

When should I sow cornflower seeds?

Sow outdoors in spring, from March to May, for flowers from early summer. An autumn sowing in September or October gives stronger plants that flower earlier the following year; protect them with a cloche or cold frame in a hard winter.

Can I grow cornflowers in a pot?

Yes. A container at least 30 cm wide and deep holds several plants. Use a free-draining compost, place it in full sun and pick the flowers regularly to keep them coming.

Do cornflowers come back every year?

Cornflowers are hardy annuals, so each plant flowers for one season and dies. Leave a few late flowers to set seed and they will often self-sow, or collect the seed and sow it again in spring.

What is your returns policy?

Changed your mind? You can return pots, gifts, accessories and other non-plant items. Email hello@growtropicals.com with your order number within 14 days of delivery, then send the item back within 14 days of telling us. You pay the return postage.

Items must come back unused and in their original condition. If an item has been used, we may reduce your refund by the value it has lost, and for used items this can be the full price.
