Dormancy/Planting
Late springRhizomes are bare with visible growth buds; plant in spring as water warms
Choose firm, healthy rhizomes; plant in spring when water temperature reaches 50°F; keep rhizomes moist before planting
Vegetative Growth
4-6 weeksShoots emerge from rhizomes; leaves unfurl and float on water surface; plant appears to be establishing
Ensure adequate water level; remove any damaged leaves; fertilize every 2-3 weeks with aquatic fertilizer; monitor for pests
Flowering
June-SeptemberFlower buds appear and open into white or pink blooms with fragrant petals; blooms last 3-5 days and close at night
Remove spent flower buds to encourage continuous blooming; maintain water quality and level; ensure 6-8 hours of sunlight daily
Seed Development
August-OctoberFlowers fade and seed pods develop underwater; leaves continue to grow; plant becomes denser
Remove seed pods if you wish to prevent self-seeding; continue fertilizing to support leaf growth; monitor water clarity
Dormancy
October-AprilLeaves yellow and decay in fall; plant withdraws energy to rhizomes for winter survival
Remove dead foliage from pond to maintain water quality; stop fertilizing; in zones 3-5, ensure pond does not freeze solid or protect rhizomes with mulch; water temperature drops below 50°F

Harvest Tips
Water lilies are ornamental flowers; cut blooms early in the morning when they have just opened for fresh arrangements (they last 3-5 days when cut). Remove spent flowers to encourage continuous blooming throughout the season. Harvest rhizomes for propagation in spring before active growth begins or in fall after dormancy sets in; divide large rhizomes with a sharp knife ensuring each section has at least one growth bud.
Fun Facts
- 🌱 Fragrant water lilies are named after Nymphs in Greek mythology and have been cultivated for over 3,000 years, featured in ancient Egyptian art and modern gardens alike.
- 🌱 The flowers bloom during the day and close at night, typically opening in early morning and closing by afternoon, a behavior called nyctinasty that protects the bloom from nighttime pests.
- 🌱 Nymphaea odorata is native to eastern North America and has become naturalized across temperate regions; in its native habitat, it was an important food source for Indigenous peoples who harvested the starchy rhizomes.
