🌱 How to Grow

  • 🗓️ When to Plant: Sow seeds outdoors after the last frost, or start indoors a few weeks before. Germination typically takes 7–14 days.
  • 📐 Spacing: Plant seeds 18–24 inches apart for the best growth and largest flower heads.
  • ☀️ Light & Soil: Full sun is ideal. These sunflowers aren't fussy about soil — average conditions work well.
  • 💧 Watering: Moderate watering while establishing. Once settled in, they're quite drought tolerant.
  • ✂️ Bloom Care: If spring blooms fade or go brown in mid-summer heat, mow off those heads to encourage fresh blooms as temperatures cool in early autumn.
