When to Grow

Start Kimono Red indoors in midwinter, 12 to 14 weeks before your last spring frost, after cold stratifying the seed for 2 to 4 weeks; sowing the previous summer works well too. Surface sow and lightly tap the seed in, since light aids germination, and hold the soil around 55 to 60 degrees F without a heat mat; sprouts appear in 15 to 25 days. Transplant into the garden after the last spring frost, 12 to 18 inches apart, so the plants are sized to flower in the cool weather they prefer.

How to Sow and Plant

  • Cold stratify seeds for 2-4 weeks.
  • Sow indoors 4-6 weeks before the last spring frost
  • Surface sow and lightly tap into the substrate.
  • Ideal soil temperature for germination is 60-70 F. A heat mat is not recommended.
  • Light aids germination.
  • Seeds should sprout in 20-45 days.

How to Grow

  • Transplant outdoors after the last spring frost.
  • Choose a location in full to partial sun with well-draining soil.
