Growth Stages

1

Seedling

3-6 months

Small plant with first true leaves appearing; delicate and requiring protected conditions

Keep in high humidity (70-80%), provide bright indirect light, maintain consistently moist soil, protect from direct sun and wind

2

Juvenile

1-3 years

Young tree establishing root system and developing characteristic trifoliate leaves; stems still herbaceous

Gradually acclimate to outdoor conditions if container-grown, maintain high humidity, mulch heavily, provide support stakes if needed

3

Vegetative Growth

2-5 years

Rapid height and canopy expansion with increasing branching; tree becoming woody and robust

Maintain consistent moisture and humidity, minimal pruning except to shape, monitor for pests in warm conditions

4

Flowering

Recurring annually once mature

Small white flowers appear in clusters; tree reaching reproductive maturity

Continue regular watering and moisture maintenance, allow natural flowering cycle, pollinator activity expected

5

Fruiting & Seed Production

Several months after flowering

Small black or dark purple berries develop from flowers; mature seeds viable for propagation

Allow natural fruit development, collect ripe fruits for seed propagation, maintain hydration during fruiting
