Growth Stages

1

Dormancy

November-March (varies by zone)

Plant rests underwater during winter months with minimal visible growth

In cold climates, move containers to deepest part of pond (below frost line) or store in cool greenhouse; in mild zones, may remain active year-round

2

Emergence

3-4 weeks in spring

Rhizome sprouts new eyes in spring; first leaves appear as unfurling pads

Keep water clean and introduce weak aquatic fertilizer; ensure adequate sunlight exposure as leaves expand

3

Vegetative Growth

4-6 weeks

Floating leaf pads expand and multiply; plant develops dense foliage with round, waxy leaves

Remove algae and debris regularly; thin crowded leaves to allow light penetration; apply aquatic fertilizer every 2-3 weeks

4

Flowering

June-September (12+ weeks)

Deep red flowers emerge on strong stems, opening in morning and closing at dusk; blooms are fragrant and 4-6 inches across

Deadhead spent flowers to encourage more blooming; maintain 6-8 hours sunlight daily; monitor water quality closely

5

Seed Development

Ongoing through growing season

If flowers are not deadheaded, seed pods develop underwater after bloom fades

Allow some flowers to mature for seed collection if desired, or remove for continuous blooming; collect mature seeds and store cool and moist

Avoid planting near:

Aggressive spreading water plants like water hyacinth Duckweed (can overtake water lily pads) Salvinia Dense algae growth

Common Pests

  • Spray with strong water stream to dislodge; introduce ladybugs; use neem oil for severe infestations; maintain good pond hygiene

  • Remove affected leaves; introduce dragonfly nymphs as predators; apply organic insecticidal soap sparingly

  • Remove infested leaves immediately; introduce aquatic insects that prey on larvae; maintain water circulation

  • Hand-pick large snails; introduce native aquatic snail predators; maintain balanced pond ecosystem

  • Ensure excellent water quality and circulation; remove decaying plant material; repot in fresh soil if needed; avoid overcrowding

Uses

🌿

Water Garden Display

Pollinator and Aquatic Habitat

Wildlife

Water lilies provide essential habitat for aquatic insects, frogs, and fish, while the flowers attract bees and other pollinators. Floating leaves offer refuge for aquatic fauna and help maintain pond ecosystem balance. [source]

💊

Traditional Water Lily Medicine

Medicinal

Nymphaea species have been used in traditional medicine systems for respiratory and digestive support. The roots and rhizomes contain compounds studied for potential anti-inflammatory properties. [source]

Harvest Tips

Water lilies are not harvested for food but rather enjoyed as ornamental blooms. Cut flowers in early morning when they first open; use a sharp knife or scissors to cut stems at an angle 12 inches below the water surface. Fresh-cut flowers last 3-4 days in a shallow bowl of water indoors. For seed collection, allow some flowers to fully mature and develop seed pods; collect when pods turn brown and feel soft; dry seeds and store in cool, moist conditions for spring planting.

Fun Facts

  • 🌱 Odorata water lilies are named for their strong, sweet fragrance—particularly noticeable in early morning hours—making them among the most fragrant water lily varieties available.
  • 🌱 Water lilies have a unique daily blooming pattern: flowers open in the morning and close by afternoon, sometimes reopening the next day if conditions are favorable.
  • 🌱 The leaves of water lilies contain specialized air chambers that keep them floating; these same adaptations allow them to thrive in very deep water where other aquatic plants struggle.
