Growing Information

Planting

  • Choose a location with full sun to ensure the richest burgundy and copper coloration.
  • Sow seeds directly outdoors after frost when soil has warmed, spacing them to allow a 12–18 inch mature spread.
  • Plant seeds 1 inch deep and water thoroughly to promote quick germination.
  • Thin seedlings once they reach several inches tall to prevent crowding and ensure sturdy growth.
  • For earlier blooms, start seeds indoors and transplant carefully once nighttime temperatures remain stable.
  • A well-draining, moderately fertile soil will help produce abundant 5–6 inch flower heads.

Maintenance

  • Provide consistent watering during the first few weeks to support strong root development.
  • Once established, these sunflowers tolerate brief dry periods but benefit from deep weekly watering.
  • Support taller stems with stakes if exposed to strong winds due to their 60–72 inch height.
  • Remove spent blooms to encourage continued flowering throughout the season.
  • Monitor for common garden pests and address early to maintain strong branching growth.

Harvest & Storage

  • Flowers reach peak color between 90 and 110 days after planting.
  • Cut blooms early in the morning for the longest vase life.
  • Remove lower leaves and place stems immediately into fresh water to maintain firmness.
