Growth Stages

1

Dormancy/Establishment

1-3 weeks

Newly planted rhizome is settling into position with minimal visible growth above water

Keep water warm (75°F+); provide bright light; do not disturb rhizome; ensure stable water conditions

2

Vegetative Growth

3-4 weeks

Multiple leaves emerge and float or extend above the water surface; plant establishes root system

Apply slow-release aquatic fertilizer tablets monthly; maintain water depth and temperature; remove any yellowing leaves

3

Budding

1-2 weeks

Small buds develop beneath the water surface or at the leaf bases; buds begin rising toward the surface

Continue regular fertilization; ensure adequate sunlight (6-8 hours daily); maintain stable water temperature

4

Flowering

2-4 months (throughout growing season in tropical climates)

Delicate white flowers with pale pink centers bloom above the water surface; flowers open in morning and close in afternoon

Deadhead spent flowers to encourage more blooms; maintain consistent water conditions; continue fertilizing every 2-3 weeks

5

Seed Development/Decline

Variable; continuous in warm climates; 2-3 months before dormancy in cooler zones

Flowers fade and seed pods may develop; in cooler climates, plant slows growth as temperatures drop

In tropical zones, plant remains productive; in temperate zones, prepare for dormancy by reducing water temperature; clean up debris
