Growth Stages

1

Dormancy/Planting

1-2 weeks

Rhizome is planted in soil-filled containers before being submerged. Little visible growth above water initially.

Plant in spring after water temperature reaches 60°F. Use heavy soil mix in pots. Position rhizome with growing tip pointed upward and just above soil.

2

Establishment & Early Growth

2-4 weeks

First leaves emerge and unfurl at water surface; thin, elongated juvenile leaves precede adult foliage.

Keep water calm to allow leaves to reach surface. Apply dilute aquatic fertilizer. Remove any floating debris.

3

Vegetative Growth

4-6 weeks

Adult pad formation with multiple leaves on petioles reaching the water surface; plant expands radially.

Thin leaves if overcrowded (remove older outer leaves to reduce shading). Continue light fertilization every 2-3 weeks. Monitor for pests.

4

Flowering

4-6 months (June-September in temperate zones)

Deep burgundy-red flowers emerge on sturdy stems, typically opening in morning and closing by afternoon. Flowers are semi-double with darker inner petals.

Deadhead spent blooms to encourage more flowering. Maintain consistent water level and temperature. Feed weekly with bloom-promoting fertilizer.

5

Dormancy/Winter Preparation

3-4 months

Growth slows as temperatures cool; leaves yellow and decline. Rhizome enters dormant state underground.

In zones 3-7, drain pond or protect rhizome with 12+ inches of water and mulch. In warmer zones, maintain minimal care. Do not fertilize.

Companion Planting

Plan your garden →

Plant with:

Water iris (Iris laevigata) Pickerel rush (Pontederia cordata) Water hawthorn (Aponogeton distachyos) Watercress Marginal sedges (Carex species) Rushes (Juncus species) Floating plants like Water lettuce (Pistia stratiotes) Submerged oxygenating plants (Elodea, Cabomba)

Avoid planting near:

Aggressive marginal plants that shade the lily Water plants with dense foliage that compete for light Fast-spreading water gardens weeds like Water hyacinth (in warm zones)

Common Pests

  • Spray affected leaves with water forcefully; use insecticidal soap; encourage beneficial insects like ladybugs

  • Remove affected leaves; handpick beetles; use neem oil; submerge infested leaves underwater for 24 hours to disrupt life cycle

  • Remove heavily damaged leaves; maintain water clarity; increase water circulation

  • Ensure proper planting depth; avoid burying crown; improve water circulation; remove infected tissue if caught early
