Growth Stages

1

Tuber Dormancy

Variable, triggered by warmth

Dormant tuber or rhizome begins to break dormancy when water warms above 60°F.

Store tubers in cool, moist sand or peat over winter if growing in cooler zones. Ensure water temperature is adequate before planting.

2

Leaf Development

2-3 weeks

Initial hairy leaves emerge reddish or bronze, unfurling and expanding in water. Leaves develop the characteristic pubescent texture and deepen in color.

Begin light fertilization with aquatic plant tablets. Ensure adequate water depth and sunlight. Monitor for debris or algae covering young leaves.

3

Vegetative Growth

3-4 weeks

Mature foliage develops with multiple floating leaves reaching 8-12 inches across. Plant establishes a robust root system and rhizome.

Apply aquatic plant fertilizer every 2-3 weeks. Thin excess leaves if overcrowding occurs. Remove any dead or damaged foliage.

4

Flowering

8-12 weeks or longer in ideal conditions

Buds form on stalks between leaves and develop into deep red, fragrant flowers that open at dusk (night-blooming) and close by morning. Multiple blooms may occur in succession.

Continue regular fertilization to support continuous blooming. Dead-head spent flowers. Ensure water level and temperature remain optimal (70-85°F).

5

Seed Development

4-6 weeks after flowering

After pollination (if fertilized), flowers develop seed pods that ripen underwater, eventually releasing seeds. Some flowers may not set seed without cross-pollination.

If collecting seeds, allow pods to mature fully underwater. Alternatively, allow seeds to naturally disperse or remove spent flowers to encourage continuous blooming.

Harvest Tips

Red lotus is not harvested for food or foliage in typical cultivation.
