Growing Conditions and Care

This easygoing wildflower thrives in USDA hardiness zones 8-10, making it well-suited to California’s Mediterranean climate and similar regions.

Sunlight: Speckled clarkia loves full sun and will produce the most flowers when it receives at least 6-8 hours of direct sunlight daily.

  • Germination: Keep soil consistently moist until seedlings emerge
  • Maintenance: Once established, minimal care needed – just occasional water during dry spells
