How to Germinate Munro’s Globemallow

How to Germinate Munro’s Globemallow (Sphaeralcea munroana)

  • Lightly scarify seeds using sandpaper or soak in warm water for a few hours to improve germination rates.
  • Sow seeds directly outdoors in fall or early spring, or start indoors 6–8 weeks before the last frost.
  • Use a sandy, well-draining seed-starting mix to mimic natural conditions.
  • Plant seeds about 1/8 inch (3 mm) deep and cover lightly with soil.
  • Maintain a temperature of 65–75°F (18–24°C) for germination, which typically takes 14–21 days.
  • Keep soil slightly moist during germination, but avoid overwatering.
  • Transplant seedlings outdoors after frost danger has passed and the plants are well-established.

Additional Tips

  • Prefers full sun and thrives in dry, rocky, or sandy soil—ideal for low-water landscapes.
  • Extremely drought-tolerant and low maintenance once established.
  • Attracts native bees, butterflies, and other pollinators with its bright orange blooms.
  • Deer-resistant and capable of surviving in poor soil conditions.
  • Deadhead flowers occasionally to encourage prolonged blooming from spring into summer.
