Phenological Markers – Pink Cedar (Tabebuia heterophylla)

1. Leaf Drop (Deciduous Behavior)
Tabebuia heterophylla is deciduous, often shedding most or all of its leaves in the dry season—typically January to March in St. Croix.

• Leaf drop is usually timed to precede flowering, leaving the tree mostly bare.
• This leafless stage enhances the visual impact of the flowers.

2. Flowering
Flowering is the tree’s most striking phenophase. Large, trumpet-shaped pink to pale lavender flowers bloom in abundance, often covering the bare branches.

• Flowering usually occurs in late dry season (February–April).
• Flowering may begin before any new leaves appear, producing a spectacular floral display.
• Flowers may fall off quickly, creating a carpet of pink beneath the tree.

3. Leaf Flush (New Growth)
After flowering, the tree enters a period of leaf flush, producing simple, ovate green leaves.

• Leaves emerge as flowering declines—usually April through May.
• New leaves may appear slightly bronze before maturing to green.

4. Fruiting
The tree produces long, slender seed pods, often 10–15 inches long, which develop after flowering.

• Pods mature through late spring and early summer (May–July).
• When ripe, the pods split open to release numerous flat, winged seeds, dispersed by wind.

5. Seasonal Synchrony
This tree displays strong seasonal cues:

• Bare branches → Mass flowering → Leaf flush → Pod development → Seed dispersal

Observation Tips:

• Note leafless phase timing each year to anticipate flowering.
• Photograph first flower appearance, peak bloom, and flower fall.
• Document pod growth and seed dispersal—especially if windblown seeds accumulate in nearby areas.
