Sunflower Red Sun is a striking heirloom variety that commands attention with its tall, branching stems reaching 5 to 6 feet, producing spectacular deep red and red-yellow blooms that serve as bold focal points in any garden. Prolific and long-blooming, Red Sun is exceptionally valuable for cut flower production, dried arrangements, and ornamental landscape plantings. Blooms reach full color in approximately 110 days, and successive sowings ensure continuous color throughout the season. Staking at the 3-foot mark is recommended in windy areas to support the tall stems when laden with developing seed heads. These vibrant flowers are outstanding pollinator magnets, attracting bees, butterflies, and other beneficial insects that enhance overall garden ecosystem health.

Germination Rate: 94%. Test Date: 7/25. TLM.

Why Choose Sunflower Red Sun?

  • Dramatic Red Blooms: Deep red and red-yellow flowers — a bold, eye-catching alternative to classic yellow sunflowers.
  • Tall Branching Habit: 5–6 foot branching stems produce multiple blooms per plant — more flowers per seed.
  • Excellent Cut Flower: Long, sturdy stems and vibrant color make Red Sun outstanding for fresh-cut arrangements.
  • Long Bloom Season: Successive sowings ensure continuous garden color from summer through fall.
  • Pollinator Magnet: Attracts bees, butterflies, and beneficial insects throughout the season.
  • Heirloom Quality: Open-pollinated and passed down for at least 75 years — grows true year after year.

Planting Tips for Success

  • Sunlight: Full sun — sunflowers thrive with 6–8+ hours of direct sunlight daily.
  • Soil: Well-drained, fertile soil with a pH of 6.0–7.5. Tolerates poor soils but performs best with good fertility.
  • Planting: Direct sow after last frost when soil temperature reaches 50°F+. Plant 1 inch deep. Can succession-sow every 2–3 weeks for continuous blooms.
  • Spacing: Thin to 12–18 inches apart for branching varieties; wider spacing produces larger blooms.
  • Watering: Water deeply but infrequently; sunflowers are drought-tolerant once established. Avoid overwatering.
  • Fertilizing: Light balanced fertilizer at planting; avoid excess nitrogen which promotes foliage over blooms.
  • Support: Stake at the 3-foot mark in windy areas to support tall stems laden with seed heads.
  • Harvesting: Cut blooms when fully open for fresh arrangements. For seeds, wait until the back of the head turns yellow-brown and seeds are plump.
