When to Grow

Sow seeds directly outdoors after the last frost, when soil temperatures reach at least 50 F. Alternatively, you can start seeds indoors 2-3 weeks before the last frost. These sunflowers prefer warmer temperatures for germination, so be sure to check your local frost dates before planting​. If you’re not sure how to find your first and last frost dates, consult our blog post 'Our Experts Answer Questions, Share Resources.'

How to Sow and Plant

Sow seeds 1/2 inch deep. Thin the seedlings to 18-24 inches apart after they emerge to ensure proper spacing, as this helps avoid overcrowding and allows better air circulation. Planting in well-draining soil enriched with compost improves growth​ as well.

How to Grow

Autumn Beauty sunflowers bloom within 70-100 days of planting, adding vibrant colors to the garden from mid-summer through early fall. It’s important to water regularly, especially during dry spells, but avoid overwatering to prevent root rot. These tall sunflowers may require staking to support their height and prevent toppling in windy conditions.

How to Save Seeds

  • When petals die back and heads begin to dry and turn brown, place a paper bag over the heads to protect seeds from birds.
  • After a few days, the heads will dry to a dark brown. Bring the heads indoors and hang them upside down in a dry area in direct sunlight for up to a week, shaking seeds free each day.
  • Store seeds in a cool, dark, dry place.
