Scabiosa atropurpurea (Pincushion Flower)

Seed Treatment

  • Cold Stratification: Store seeds in a damp paper towel inside a sealed plastic bag in the refrigerator for 1–2 weeks before planting.
  • After stratification, soak seeds in warm water for 12–24 hours to improve germination.
  • If seeds begin to germinate in the bag, remove them immediately and plant in moist soil.

When & Where to Sow

  • Indoors: Start seeds 6–8 weeks before the last expected frost.
  • Outdoors: Direct sow after the danger of frost has passed.
  • Choose a sunny spot with well-draining soil.

Optimum Temperature for Germination

  • Ideal soil temperature: 68–75°F (20–24°C)
  • Use a heat mat if starting indoors in cooler conditions.

Germination Time

  • Germination typically occurs in 7–14 days.
  • Maximum germination time: 21 days

Sowing Instructions

  • Sow seeds ¼ inch (0.5 cm) deep in moist, well-drained soil.
  • Lightly cover with soil and gently press down.
  • Keep soil consistently moist but not soggy.
  • Use a humidity dome or clear plastic wrap indoors to maintain moisture.

After Germination Care

  • Remove any cover once seedlings appear.
  • Provide bright light or place under grow lights for 14–16 hours/day.
  • Thin or transplant seedlings when they have 2–3 true leaves, spacing them 10–12 inches (25–30 cm) apart.
  • Harden off indoor seedlings before transplanting outdoors.

Water & Maintenance

  • Water regularly but avoid overwatering; allow the topsoil to dry slightly between waterings.
  • Deadhead faded flowers to encourage continuous blooming.
  • Scabiosa thrives in fertile soil—consider adding compost before planting.

Bonus Tips

  • Loved by bees and butterflies!
  • Great for cut flowers—harvest when blooms are just opening.
  • May self-seed in favorable conditions.
