Flowering of Cinnamomum verum

Understanding the flowering stage is important for seed production, phenology tracking, and plantation management—especially if you plan to develop elite mother trees.

Flower Characteristics

  • Color: Creamy white to pale yellow
  • Size: Small (about 3–6 mm)
  • Arrangement: Terminal or axillary panicles
  • Fragrance: Mild, slightly sweet but not showy

Flowers are not ornamental, but biologically important for reproduction.

Flowering Season (Philippines)

  • Typical period: March to May
  • Triggered by:
    • Dry season transition
    • Increased sunlight exposure

Flowering Age

  • Seed-grown trees: 3–5 years
  • Grafted / clonal trees: 2–3 years (earlier)

Pollination

  • Mainly insect-pollinated
  • Attracts:
    • Small bees
    • Flies

Fruiting After Flowering

  • Fruit type: Small drupe
  • Color when mature: Purple to black
  • Timeline:
    • Flowering → fruit set: ~2–3 months
    • Fruit maturity: June–August

Factors Affecting Flowering

Environmental

  • Sunlight intensity
  • Seasonal dry period
  • Temperature stability (25–30°C)

Management

  • Pruning (can delay or stimulate flushing)
  • Nutrient availability
  • Tree maturity

Practical Plantation Insight

For Commercial Cinnamon Production:

  • Flowering is not the primary goal
  • Focus is on:
    • Vegetative growth
    • Coppicing for bark production

For Breeding & Seed Production:

  • Select flowering trees with:
    • High oil yield
    • Superior bark quality
  • Establish a mother tree block

Agroforestry Integration Insight

In systems integrated with:

  • Aquilaria malaccensis

Flowering stage helps:

  • Identify elite genetic lines
  • Support propagation programs (grafting / layering)
  • Improve long-term plantation quality

Pro Tip (Advanced)

If your goal is vegetative production (bark):

  • Suppress excessive flowering by:
    • Regular pruning
    • Nitrogen-rich fertilization

If your goal is seed production:

  • Allow trees to mature and avoid heavy coppicing
