Cosmos - Seashells (Cosmos bipannatus) Heirloom Mixed Cosmos Sea Shells Flower


18 to 60 inches

Gorgeous! Waves of quilled blossoms of uniquely rolled, ruffled, hollow, and tube shaped petals that radiate from the centre in shades of white, pink, or carmine red, sit atop typical airy foliage. Blooms summer to frost. Deadheading promotes continuous blooming. Well branched plants up to 6 ft. tall thrive in difficult sunny and dry spots, flowering freely all summer through to fall.

Great for cut flowers, cottage gardens and borders. Cut and come again; cutting stems for bouquets encourages more side shoots. Outstanding when grown in large masses or mixed with other coloured flowers/cosmos. 

  • Full sun/ part sun
  • Prefers well-draining soil
  • Direct sow as soon as soil is warm (late spring) or start indoors early spring, cover seed lightly and plant out after frost danger.
  • Germinates at 20C
  • Attracts butterflies and bees
  • Harvest seeds: at the end of the season and after blooms die down, harvest seeds when the top of the pod is hard (and pointy) to the touch. Store in a dark cool place.
