Growth Stages

1

Germination

1-2 weeks

Tiny seedlings with cotyledons (seed leaves) emerge within 7-10 days under light conditions.

Keep soil moist but not waterlogged. Provide bright light. Do not cover seeds with soil.

2

Seedling

3-4 weeks

Delicate plants develop first true leaves; growth is relatively slow. Plants remain small and compact.

Thin seedlings to proper spacing to reduce competition. Reduce watering frequency. Avoid fertilizer.

3

Vegetative/Growth

3-4 weeks

Bushy mounding plants develop multiple stems and feathery blue-green foliage. No flowers yet but plant fills out nicely.

Continue moderate watering. Avoid excessive nitrogen fertilizer. Deadhead spent flowers when they appear to encourage more blooms.

4

Flowering

6-12 weeks (spring through early fall, depending on climate)

Semi-double to double golden-orange flowers with ruffled petals emerge continuously. Plant may reach 12-18 inches tall.

Deadhead regularly to extend blooming through summer. Water moderately; reduce watering during cool periods. No supplemental fertilizer needed.

5

Seed Set/End of Season

Variable; continuing until frost or sustained heat

Flowers fade and elongated seed pods develop. Foliage may decline if temperatures rise above 85°F consistently.

Allow some flowers to remain for self-seeding if desired. Collect seed pods for saving or allow to scatter naturally. Plants decline in extreme heat; may rest in summer.

Fun Facts

  • 🌱 California Golden Poppy is the official state flower of California and has been since 1903; it blooms so profusely in spring that hillsides appear to be on fire.
  • 🌱 The flowers exhibit heliotropic behavior, opening in full sunlight and closing at dusk or on overcast days—this is an adaptation to conserve pollen in cool conditions.
  • 🌱 Mission Bells will readily self-seed in ideal conditions, creating naturalized drifts in subsequent seasons and providing year-after-year color with minimal effort.
