Grow White Cornflower from Seeds

  • Tolerating a variety of soil types, the optimum temperature for germination should be 15-20 degrees celsius, with germination taking between 5-10 days.
  • 4-6 weeks before the last spring frost seeds can be started outdoors. For better germination, sow indoors somewhere which receives lots of sunlight.
  • Alternatively, direct sow seeds outside with a depth of 1/8 to ¼ inches after the danger of frost has passed. Do not allow the growing medium to dry out, maintaining moisture and warmth.
  • Ensure the seeds are well pressed as darkness aides germination.
  • When seedlings are between 2 and 3 inches high, thin to 10 to 12 inches apart while replanting any thinned plants.
